Installing the LightStream 1010 ATM Switch

This chapter describes the procedures for rack-mounting, connecting the cables, and powering up the LightStream 1010 ATM switch at your site.

fig_1.gif Caution Before installing the chassis in a rack, read the section "Safety with Electricity" in the chapter "Preparing for Installation" to familiarize yourself with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.


Rack-Mounting the Switch

A rack-mount kit is included for mounting the switch in a standard 19-inch (48.7-centimeter) equipment rack with two unobstructed outer posts.

Following is the procedure for attaching the rack-mount kit and installing the switch in a wiring closet rack. Two or more people are needed to perform this procedure.

Be sure you have at least three or four feet of clearance behind the rack for maintenance. The intake and exhaust ports for cooling air are located on the front and rear and both sides of the chassis, so multiple switches can be stacked with little or no clearance in a rack. The chassis is 10.36 inches (25.9 centimeters) high.

Before rack-mounting the LightStream 1010 ATM switch, confirm that your rack-mount configuration conforms to the following criteria:

Caution Before you mount the switch in a rack, make sure that: the rack is secure and in no danger of falling over; the area around the rack does not exceed a maximum ambient temperature of 104°F (40°C); and sufficient airflow exists around the rack.
Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface modules. These handles were not designed to support the weight of the chassis. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

Refer to the section "Safely Lifting the Chassis" in the chapter "Preparing for Installation."


Tools for Installation

Following are the tools and equipment needed to install the chassis:

If you are installing the chassis in a rack, you will also need the following:


Installing the L Brackets

The rack-mount kit is for a standard 19-inch (48.7-centimeter) rack with a minimum depth (between the front and rear mounting posts) of 19.25 inches (39.4 centimeters) and a maximum depth of 32 inches (82 centimeters). The width between the two front equipment mounting strips (left front and right front) must be at least 17.75 inches (45.5 centimeters). Two L brackets (which you attach to either the front or back of the chassis) and the mounting posts connect the chassis to the rack. Some equipment racks provide a power strip along the length of one of the rear posts. If your rack has this feature, consider the position of the strip when planning fastener points and, before you install the L brackets on the chassis, determine whether you are going to install the chassis from the front or the rear of the rack.

Note It is important that the rack be unobstructed. This kit is not suitable for use with other racks, such as telco-type equipment racks, or those with obstructions, such as a power strip. Access to the switch modules and power supplies must be unimpaired.

Take the following steps to attach the two L brackets to the switch chassis:

Step 1 Place the chassis on the floor or on a sturdy table as close as possible to the rack, with clearance to allow you to move around the chassis.

Step 2 Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The depth must be at least 19.25 inches (39.4 centimeters), but not greater than 32 inches (81 centimeters).

Step 3 Measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45 centimeters) wide. (The chassis is 17.25 inches [43 centimeters] wide and must fit between the mounting posts.)

Step 4 Open the rack-mount kit and refer to the component checklist in Table 4-1 to verify that all parts are included.

Table 4-1 : Rack-Mount Kit Checklist

Quantity Part Description Received
2 L brackets (left and right)
6 M4 Phillips countersunk-head screws
8 12-24 x 3/4-inch Phillips binder-head screws
8 10-32 x 3/4-inch slotted binder-head screws

Step 5 Depending on your installation, remove the six cover attachment screws from either the front or the rear of the switch. (See Figure 4-1.)

Note Figure 4-1, Figure 4-2, and Figure 4-3 illustrate attaching the front of the switch to the rack. You can also attach the rear the switch to the rack, if your rack configuration permits.

Note No shelf is required with this assembly; the L brackets support the chassis in the rack.


Installing the Chassis in the Rack

The L brackets attach the chassis to the front mounting posts. You can mount the L brackets on either the front or rear of the chassis, whichever end will be in the front of the rack.

fig_8.gif Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

  • This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

  • When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

    fig_9.gif

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface modules. These handles were not designed to support the weight of the chassis. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

Follow these steps to install the switch in an open rack that allows you to slide the chassis in from the front.

Step 1 Two people are required to perform this step.While referring to Figure 4-3, with a person positioned at either side of the chassis, grasp the bottom edge of the chassis with one hand near the front and the other near the back. Slowly lift the chassis in unison. Avoid sudden twists or moves to prevent injury.

Step 2 Position the chassis in the rack as follows:

  • If the chassis front panel will be in the front of the rack, insert the rear of the chassis between the rack posts, and align the five mounting holes in the L bracket with five mounting holes in the equipment rack.

  • If the rear of the chassis will be in the front of the rack, insert the front of the chassis between the mounting posts, and align the five mounting holes in the L bracket with the five mounting holes in the equipment rack.

Figure 4-3 : Installing the Switch in the Rack

Step 3 A third person should install the 10-32 x 3/4 inch slotted binder-head mounting screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.

Step 4 Use your tape measure and level to ensure that the chassis is installed straight and level.

Step 5 At the front of the chassis, perform the following steps:

  • Check the ejector levers and ensure that the Asynchronous Transfer Mode Switch Processor (ASP) and all Carrier Modules (CAMs) and Port Adapter Modules (PAMs) are securely installed.

  • Tighten any captive installation screws that are loose on the ASP, CAMs, and PAMs.

Step 6 Make sure that your path to the rack is unobstructed.

The rack-mount installation is now complete.


Connecting Interface Cables

This section describes the basic network connections---Ethernet and ATM--- that you make to the switch. Using the Port Configuration Worksheet helps you to make connections and later configure each interface without having to access the rear of the chassis to check port addresses. See the section "Using the Port Configuration Worksheets" in the appendix "Configuration Worksheets."


External Cabling Guidelines

Use the following guidelines to assist you in properly connecting the external network cables to your switch.

  • Make certain that you connect the correct interface types.

  • Avoid crossing high-power cables with interface cables.

Whenever possible, avoid crossing high-power cables with interface cables to prevent interference in some interface types.

  • Do not defeat cable strain-relief systems.

Most interfaces provide some type of strain relief to prevent the cables from being accidentally disconnected. Use all strain-relief devices provided to prevent potential problems caused by inadvertent cable disconnection.

  • Verify proper interface cabling before starting the system.

Before applying power to the system, prevent unnecessary problems or component damage by double-checking your cabling.

  • Verify all cabling limitations before applying power to the system.

When setting up your system, you must consider a number of cabling related factors required for your connections. For example, when using EIA/TIA-232 connections, be aware of the distance and electromechanical interference (EMI) limitations. For cabling distances and other requirements, refer to the section "Site Requirements" in the chapter "Preparing for Installation."

  • Check the power cord and power supply for compatibility with your power service.

Check the labels on the equipment and ensure that the power service at your site is suitable for the chassis you are connecting. If you are not sure, refer to the section "Site Requirements" in the chapter "Preparing for Installation."

fig_2.gif

Warning A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the chassis to that receptacle. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."

Note After installing all the rear panel cables and powering up the system, refer to the publication LightStream 1010 ATM Software Configuration Guide.

If the switch fails to operate, refer to the chapter "Confirming the Installation" to help isolate the problem, and then notify a customer service representative.

The sections that follow provide illustrations of the connections between the switch interface ports and your network(s). Interface cables and equipment, such as Ethernet transceivers and interface cables, should already be available and in place. If they are not, refer to the following section "Ethernet Connections," for descriptions of the equipment you need for each interface type to complete the connection to your network.


Ethernet Connections

Most Ethernet connections do not require a transceiver on the interface cable. Figure 4-4 shows examples of typical connections. For a description of the connection equipment, refer to the section "Ethernet Connection Equipment" in the chapter "Preparing for Installation."

ATM Synchronous Optical Networks Connections

All Synchronous Optical Network (SONET) ATM interfaces are full-duplex. You must use the appropriate ATM interface cable to connect the ATM PAM with an external ATM network.

The ATM PAMs provide an interface to ATM switching fabrics for transmitting and receiving data at up to 622 Mbps bidirectionally.

The fiber-optic ATM PAM can support interfaces that connect to the following physical layers:

  • SONET 155-Mbps MM fiber-optic---STS-3C

  • SONET 155-Mbps SM fiber-optic---STS-3C

  • SONET 622-Mbps SM fiber-optic---STS-12C

  • SONET 622-Mbps MM fiber-optic---STS-12C

Connect the ATM interface cables as shown in Figure 4-5. For detailed descriptions of ATM cabling requirements, refer to the sections "Distance Limitations" and "ATM Synchronous Optical Networks Connections" in the chapter "Preparing for Installation."

Figure 4-5 : ATM Fiber-Optic Connections

fig_5.gif Warning Do not stare into the laser beam. To see translated versions of this warning, refer to the appendix "Translated Safety Warnings."


ATM Unshielded Twisted-Pair Connections

The unshielded twisted-pair (UTP) ATM interface is full duplex. You must use the appropriate ATM interface cable to connect the ATM PAM with an external ATM network.

The ATM PAMs provide an interface to ATM switching fabrics for transmitting and receiving data at up to 155 Mbps bidirectionally; the actual data rate is determined by the physical layer interface module (PLIM).

  • The UTP ATM PAM can support interfaces that connect to SONET 155-Mbps UTP-5---STS-3C.

Connect the ATM interface cables as shown in Figure 4-6. For detailed descriptions of ATM cabling requirements, refer to the section "Distance Limitations" and the section "ATM Synchronous Optical Networks Connections" in the chapter "Preparing for Installation."

Figure 4-6 : ATM UTP Connections

ATM Coaxial Connections

All coaxial ATM interfaces are full-duplex. You must use the appropriate ATM interface cable to connect the ATM PAM with an external ATM network.

The ATM PAM provides an interface to ATM switching fabrics for transmitting and receiving data at 34 and 45 Mbps bidirectionally.

The ATM PAM can support interfaces that connect to the following physical layers:

  • DS-3 45-Mbps coaxial cable

  • E3 34-Mbps coaxial cable

Connect the ATM interface cables as shown in Figure 4-7. For detailed descriptions of ATM cabling requirements, refer to the section"Distance Limitations" and the section "ATM Synchronous Optical Networks Connections" in the chapter "Preparing for Installation."

Figure 4-7 : ATM Coaxial Connections

Serial Connections

The ASP CONSOLE port supports a data communications equipment (DCE) EIA/TIA-232 interface type and mode. For descriptions and illustrations of each connector type, refer to the section "EIA/TIA-232 Connections" in the chapter "Preparing for Installation." For cable pinouts, refer to the section "Preparing Network Connections" in the chapter "Preparing for Installation."

When connecting a serial device, consider the cable as an extension of the switch for an external connection; therefore, use null-modem cable to connect the switch to a remote DCE device such as a modem or data service unit (DSU), and use a straight-through cable to connect the switch to a data terminal equipment (DTE) device such as a terminal or PC. (See Figure 4-8.)

Figure 4-8 : Serial Port Adapter Cable Connections

Connecting the Console Terminal

The system console port on the ASP is a DCE DB-25 receptacle for connecting a data terminal, which you will need to configure and communicate to your system. The port is located on the ASP faceplate and is labeled CONSOLE, as shown in Figure 4-8.

Note The console port is an asynchronous serial port; any devices connected to this port must be capable of asynchronous transmission. (Asynchronous devices are the most common type of serial device; for example, most modems are asynchronous devices.)

Before connecting the console port, check your terminal's documentation to determine the baud rate. The baud rate of the terminal must match the default baud rate (9600 baud) of the terminal you will be using. Set up the terminal as follows:

  • 9600 baud

  • 8 data bits

  • No parity

  • 1 stop bit

Use the proper null-modem or straight-through cable to connect a terminal or modem to the console port on the ASP; then follow the steps in the section "Starting the System."


Connecting Power

This section describes the procedures to apply power to the LightStream 1010 ATM switch at your site. Connect an AC-input power supply, as follows:

Step 1 On one power supply, plug in the power cord.

Step 2 Connect the power-supply cord to an input line. (See Figure 4-9.)

Figure 4-9 : Power Cord Connection

h5606.gif


Connecting Redundant Power

Connect the redundant power supply to a separate input line. Connect the redundant AC-input power supply as follows:

Step 1 On the redundant power supply, plug in the power cord.

Step 2 Connect the redundant power supply cord to an input line other than the initial power supply line. (See Figure 4-9.)


Starting the System

When all interfaces are connected, perform a final check of all connections then take the following steps to check the components and power up the system.

Step 1 Check the following components to make sure they are secure:

  • Each module is inserted all the way into its slot and all the captive installation screws are tightened.

  • All interface cable connections are secured.

  • Each power supply is inserted all the way into its bay, and the captive installation screw is tightened.

  • All power-supply cables are securely connected to the power supply.

Step 2 Check the external power connections; the power-supply switches should still be OFF:

  • At the power source end of the power cable, make sure the connector is securely installed in a grounded outlet and that the source power is within the range labeled on the back of the switch.

  • When two supplies are present, make sure that the second cord is connected to a separate line from the first, if possible.

Step 3 Check the console terminal and make sure it is ON.

Step 4 Turn the power supply(ies) ON.

Step 5 After both power supplies are switched ON, the PS0 and PS1 LEDs on the ASP faceplate will be green.

Step 6 Listen for the system fan assembly and check the fan LED on the ASP. You should immediately hear it start operating.

Step 7 While the system initializes, the status LED on the ASP is orange until the boot is complete. Refer to the chapter "Confirming the Installation" for troubleshooting procedures.

During the boot process, the status LED on all interfaces is orange. Some LEDs may go on and remain on or go out and go on again for a short time. Some LEDs, such as the link LED, will stay on during the entire boot process. If an interface is already configured, the LEDs may go on steadily as they detect traffic on the line. Wait until the system boot is complete before attempting to verify the module LED indications.

When the system boot is complete (it takes a few seconds), the ASP begins to initialize the PAMs. During this initialization, the LEDs on each PAM behave differently (most flash on and off). The status LED on each PAM goes on when initialization has been completed, and the console screen displays a script and system banner similar to the following:
