Setting Up the Chassis

You can set the chassis on a desktop or install it in a rack. Use the procedure in this section that best meets the needs of your network:

Warning When installing the unit, the ground connection must always be made first and disconnected last.

Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

Setting the Chassis on a Desktop

The location of the chassis is extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. The following information will help you to plan the location of the chassis:

Plan for access to both front and rear panels of the chassis.
Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

Attach the rubber feet as shown in Figure 3-1. Rubber feet are included in the accessory kit that shipped with your access server.

Figure 3-1: Attaching the Rubber Feet

Rack-Mounting the Chassis

You can mount the chassis in a 19-, 23-, or 24-inch equipment rack. The following information will help you plan your equipment rack configuration:

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.
When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.
When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power.
Install the chassis and external devices to which it will connect in a contiguous stack.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Required Tools and Equipment

You need the following tools and equipment to rack-mount the chassis:

Number 2 Phillips screwdriver (not included)
Screws for attaching the chassis to the rack (not included)
Rack-mount brackets

: The chassis ships with one set of 19-inch and 23- or 24-inch brackets.

Figure 3-2: Identifying the Rack-Mounting Brackets

Attaching the Brackets

To install the chassis in a rack, attach the brackets in one of the following ways:

With the front panel forward (see Figure 3-3)
With the rear panel forward (see Figure 3-4)
In a center-mount telco rack (see Figure 3-5)

Note Although the installations that follow show only the 19-inch brackets, the procedure is the same for the larger brackets for use in a 23-or 24-inch rack.

Connecting to the Network

This section describes how to connect the access server to your network. The cables required to connect the access server to a network are not provided. For ordering information, contact customer service or see the appendix "Cabling Specifications for the Universal Access Server" for cable and port pinouts.

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Caution If the access server is configured with fewer than three feature cards, make sure that a blank slot cover is installed over each open slot to ensure proper airflow.

Note The access server comes with all cards already installed, unless you order a card separately as a spare. Refer to the appendix "Maintaining the Universal Access Server" for card installation instructions.

Connecting to an Ethernet Network

You can connect the access server to an Ethernet network by using a straight-through RJ-45-to-RJ-45 Ethernet cable to connect the Ethernet 10BaseT or 10/100BaseT port to an Ethernet hub. (See Figure 3-7.)

Figure 3-7: Connecting to an Ethernet Hub (10BaseT Shown)

Connecting to a WAN

You can connect the access to a WAN in the following ways:

Use a straight-through RJ-45-to-RJ-45 cable to connect each T1/PRI port to an RJ-45 jack. (See Figure 3-8.)
Use an E1 cable to connect each E1/PRI port to an E1 channel service unit (CSU)/data service unit (DSU). (See Figure 3-9.)

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.

Figure 3-8: Connecting to an RJ-45C (T1) Jack

A 10-position rotary switch (labeled IMP SEL) allows you to chose the number of ports that are terminated as 75-ohm unbalanced lines. The LED labeled 120 at each port indicates the input impedance of that port. If the LED is on, it indicates the impedance of the port is set to 120 ohms. If the LED is off, it indicates the impedance of the port is set to 75 ohms.

If you are connecting to a port with 75-ohm input impedance, use an RJ-45-to-75-ohm coaxial cable adapter and plug it into a port with the 120 LED off.

Warning This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.

Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.

Warning The E1 interface card may only be installed in an ACA-permitted customer equipment or a Data Terminal Equipment (DTE) that is exempted from ACA's permit requirements. The customer equipment must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them.

Connecting the Console Terminal and Modem

Use the console terminal for local administrative access to the access server. You can only connect a terminal to the console port. You can use the auxiliary port to connect a terminal or a modem for remote access to the access server.

Connecting to the Console Port

To connect a terminal (an ASCII terminal or a PC running terminal emulation software) to the console port on the access server:

Step 1 Connect the terminal using an RJ-45 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter. The adapters provided are labeled TERMINAL. Other types of adapters are not included. (See Figure 3-10.)

For additional information on rollover cable pinouts, see the appendix "Cabling Specifications for the Universal Access Server."

Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.

Figure 3-10: Connecting the Console Terminal

Connecting a Modem to the Auxiliary Port

To connect a modem to the auxiliary port, follow these steps:

Step 1 Connect a modem to the auxiliary port on the access server using an RJ-45 rollover cable with an RJ-45-to-DB-25 adapter. The adapter provided is labeled MODEM. (See Figure 3-11.)

Step 2 Make sure that your modem and the auxiliary port on the access server are configured for the same transmission speed (38400 baud is typical) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.

Figure 3-11: Connecting a Modem to the Auxiliary Port

Connecting to the Alarm Port

Do not connect to the three-pin alarm port. The alarm port is disabled. It is a future enhancement that is not supported by current versions of the system software or the feature cards.

Supplying Power

The access server is available with either an AC or DC power supply. You can also order a power supply as spare if you decide later that you need a different type of power supply or the power supply fails.

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

Connecting the AC Power Cord

Take these steps:

Step 1 Connect one end of the power cord to the power connector on the rear panel of the access server. (See Figure 3-12.)

Step 2 Connect the other end of the power cord to the power outlet.

Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.

Step 3 Power ON the access server.

The internal power supply fan should power on.

Figure 3-12: Connecting the AC Power Cord

Wiring the DC Power Supply

If you ordered the access server with a DC power supply, follow the procedure in this section to wire the terminal block.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a Listed and Certified fuse or circuit breaker no larger than 60 VDC, 15A is used on all current-carrying conductors.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Note This product is intended for installation in restricted access areas and is approved for connection using 12 or 14 AWG copper conductors only. The installation must comply with all applicable codes.

Refer to Figure 3-13 and follow these steps to wire the terminal block:

Step 1 Note the orientation of the DC power supply. The power supply cord should have three wires: +48 VDC, -48 VDC, and a safety ground (green wire).

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to +), and negative to negative (neutral to -). Note that the ground wire should always be connected first and disconnected last.

Caution In a DC power supply installation do not connect the -48 VDC return to chassis ground at the Cisco AS5300. A single-point ground is recommended at the power distribution rack.

Step 2 Strip off a quarter of an inch (1/4 inch [0.625 cm]) of insulation on the safety ground, +48 VDC, and -48 VDC input wires.

Step 3 Install the safety ground (green wire) into the terminal block ground connector and tighten the locking screw. Ensure that no bare wire is exposed.

Caution Do not overtorque the terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb.

Step 4 Insert the +48 VDC wire into the terminal block positive connector (+) and tighten the locking screw. Ensure that no bare wire is exposed.

Step 5 Insert the -48 VDC wire into the terminal block negative connector (-) and tighten the locking screw. Ensure that no bare wire is exposed.

Step 6 Secure the power supply cord to the cable strain-relief clamps on the DC power supply with cable ties.

Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position.

Step 7 Power ON the access server.

The internal power supply fan should power on.
