STRATM Seismic Anchoring

This section describes installing the STRATM cabinet with the optional stability plate for seismic anchoring. If the stability plate is not present, go to the next section. To set up the STRATM cabinet with the stability plate:

Step 1 Use the dimensions in Figure 3-1 to drill the holes for installing the stability plate.

Step 2 Remove the stability plate from the inside-bottom of the STRATM cabinet. Save these nuts and bolts.

Step 3 With the user-provided anchoring bolts, attach the stability plate to the floor.

Step 4 Roll the STRATM cabinet over the stability plate as Figure 3-2 illustrates.

Step 5 Using the nuts and bolts from the shipping setup, secure the STRATM cabinet to the stability plate.

Figure 3-1 : Stability Plate Dimensions

System Installation

Installing an IGX requires the following tools and equipment:

• Box knife (or equivalent)
  

• Flat blade screwdriver set
  

• Phillips screwdriver set, which must include a No. 1 size for front card installation (the No. 1 phillips comes on a combination tool provided by StrataCom)
  

• Grounding wrist strap
  

• A variety of wrenches, possibly including an adjustable wrench or channel locks, for raising and lowering cabinet feet (for example, the STRATM Cabinet requires a 1 3/8" wrench, and the stand-alone requires a 5/8" wrench)
  

• 5/32" Allen wrench for opening and closing the door latch (comes on a combination tool provided by StrataCom)
  

Rack-mount systems come with the parts described in the assembly instructions. As the instructions for DC-powered systems explain, the user provides the DC-power cable.

Stand-Alone System Installation

StrataCom stand-alone systems come with all components installed in the cabinet. So, the installation steps consist of placing the unit at its operational location, unpacking it, and verifying the structural and power connection integrity before turning on the power. Note that a stand-alone cabinet is 19.9" wide. The adjustable levelers require a 5/8" wrench. If the system has an AC power source, go to the "AC Power Connections"section. If the system has a DC power source, go to the "DC Power Connections" section.

IGX 16 Rack Mount Installation

The rack-mount IGX 16 fits in a 19 inch (48.25 cm.) rack. The front of each assembly chassis has flanges that serve as the front mounting brackets. The assembly kit contains other brackets for different mounting setups. The following order of component installation is the most convenient and efficient. For some of these components, separation sections are named that contain detailed installation steps.

1. Optional AC power assembly
   

2. Cooling unit
   

3. Card cage
   

4. Exhaust plenum
   

The miscellaneous parts kit for rack systems contains brackets for both a STRATM cabinet and a user-supplied rack. The kit includes mid-mount brackets for open racks.

The rear-mount brackets attach to the rear vertical rail in a STRATM cabinet. Each of these brackets has a horizontal flange upon which the back of each IGX component rests. The front of each assembly chassis has flanges that serve as the front mounting brackets.

Caution If an IGX is mounted in a user-supplied cabinet, be sure an unrestricted air flow is available in and out of the enclosure. If necessary, contact the ISC for assistance.

To install the IGX in a rack:

Step 1 Decide on the IGX location. See Figure 3-3 for dimensions (Figure 3-4 for metric).

Caution When moving a STRATM cabinet, do not push the cabinet at its sides. Instead, grip its front or back edges.

Step 2 To install the optional AC power supply kit, do the steps in the "Installing the AC Power Supply Assembly" section later in this chapter.

Step 3 To install the cooling unit, do the steps in the "Installing the Cooling Unit" section later in this chapter.

Step 4 Position the IGX card cage so that the back of it faces the rack.

Caution An empty IGX card cage weighs 75 pounds (34 Kgs.) and requires a 2 or 3-person lift to move into place.

Figure 3-3 : IGX 16 Rack Mounting Dimensions

Step 5 With one person on each side of the card cage, lift and slide it into the rack.

Step 6 Attach the cabinet to the rack with 8 #10-32 machine screws (from the kit).

Step 7 If the system is DC-powered, see the "DC Power Connections"section. For AC-powered systems, see the "Installing the AC Power Supply Assembly" section.

Caution Make sure that mounting the equipment does not create a hazardous condition due to uneven mechanical loading. The equipment rack should be securely supported.

IGX 32 Rack Mount Installation

The IGX 32 is designed for mounting in a 19 inch (48.25 cm.) equipment rack. The following order of component installation is the most convenient and efficient. For some of these components, separation sections are named that contain detailed installation steps.

1. Optional AC power assembly
   

2. Lower cooling unit
   

3. Lower card cage
   

4. Upper card cage
   

5. Ribbon cables for connecting upper and lower backplanes
   

6. Card cage tunnel around backplane ribbon cables
   

7. Upper cooling unit (also called booster fan unit)
   

8. Exhaust plenum
   

The miscellaneous parts kit contains brackets for rack-mounting in either a STRATM cabinet or a user-supplied rack. The kit includes mid-mount brackets for open racks. For a STRATM cabinet, the rear-mount brackets attach to the rear vertical rail. Each of these brackets has a horizontal flange upon which the back of an individual component rests. The front of each assembly chassis has flanges that serve as front mounting brackets.

Caution If an IGX goes in a user-supplied cabinet, be sure air can freely flow in and out of the enclosure.

Caution When moving a STRATM cabinet, do not push the cabinet at its sides. Instead, grip the front or back edges.

Step 1 Refer to Figure 3-4 for component dimensions. Note that, although Figure 3-4 shows mid-mount and rear-mount brackets, these brackets are not normally used together.

Step 2 To install the optional AC power supply kit, do the steps in the "Installing the AC Power Supply Assembly" section next.

Step 3 To install the cooling unit, do the steps in the "Installing the Cooling Unit" section later in this chapter.

Step 4 Install the brackets for the card cages.

Step 5 Position the IGX card cage so the back of it faces the front of the cabinet.

Figure 3-4 : IGX 32 Rack Mounting Dimensions

Caution An empty card cage requires a 2 or 3-person lift to move.

Step 6 With one person on each side of the card cage, lift it into the rack. In a STRATM cabinet, rest the back of the card cage on the rear-bracket flange.

When mid-mount brackets are used, screw the card cage to the brackets with #10-32 machine screws from the miscellaneous parts kit.

Step 7 Secure the front of the card cage to the front of the rack with #10-32 machine screws from the miscellaneous parts kit.

Warning Make sure that mounting the equipment does not create a hazardous condition due to uneven mechanical loading. The equipment rack should be securely supported.

Step 8 The folded ribbon cables that connect the upper and lower backplanes pass through a cut-out space in the card cages. The cables connect to two, 100-pin connectors on the front of each backplane. See Figure 3-5. If NPM cards are present, these and possibly other front cards need removing prior to ribbon cable installation.

Connect the cable from the upper connector of the upper backplane to the upper connector in the lower backplane.

Connect the cable from the lower connector of the upper backplane to the lower connector in the lower backplane.

Step 9 A two-piece conduit called the card cage tunnel surrounds the ribbon cables and sits in the cut-out space of the card cages. Fit the pieces of the card cage tunnel around the ribbon cables and screw this unified piece into the cut-out space. Figure 3-5 shows the card cage tunnel in its normal location and prior to assembly.

Step 10 Slip the ribbon cables through the fastener clamps, then attach the fastener clamps (which include a self-adhesive base) to the side of the card cage. See Figure 3-5.

Step 11 If this is an AC-powered system, do the procedures in the "Installing the AC Power Supply Assembly" section later in this chapter.

Step 12 If this is a DC-powered system, go to the "DC Power Connections" section later in this chapter.

Figure 3-5 : IGX 32 Backplane Connector Cables

Installing the AC Power Supply Assembly

If the IGX node is to be AC-powered, proceed with this section. In a rack-mount system, the AC Power Supply Assembly is shipped separately (as are all the other assemblies). The first assembly to install in a rack-mount system is the AC power supply assembly.

The AC power supply assembly consists of the following items:

• Power supplies---up to a maximum of six
  

• Power supply tray
  

• Power and sense cables between the AC power module and Power Entry Back Card (PE-BC)
  

• Dummy cover panels for unused power supply slots
  

• Mounting brackets and screws
  

• Air inlet bezel
  

Power supply installation or replacement requires the following tools:

• Flat blade screwdriver set
  

• Phillips screwdriver set
  

Understanding the AC Power Supply Configuration

The setup for power supplies depends on the number of AC power inputs, the IGX model, and the number of cards in the system. The minimum configuration is one AC source and one supply. This minimum number applies to the IGX 16: with 12 or fewer cards, 1 supply is enough. Figure 3-6 illustrates the alphanumeric slot designations in a full tray. The paragraphs that follow refer to these designations.

Figure 3-6 : Power Supply Slot Designations

Redundancy

Two types of redundancy exist in the AC power supply configuration. One redundancy is that of AC power inputs. A redundant AC power source from a building circuit that is separate from the other AC circuit provides backup if one AC circuit at the site fails. The other redundancy is that of the 875-Watt power supply modules. Redundancy of the 875-Watt supplies provides a backup if a supply fails.

In supporting the two types of redundancy, power supply arrangements differ, as follows:

• When a system uses two AC inputs, the number of supplies on the left and right sides must match. For example, if a system with dual AC inputs has four supplies, the supplies must occupy slots A, B, D, and E.
  

• When a system uses one AC source, the number of supplies on the left and right sides can differ. For example, three supplies on the left and one on the right is permissible.
  

Power Supply Quantities

Table 3-1 shows the required number of power supplies for the different IGX systems. In Table 3-1, the locations for primary (or minimal) power supplies are marked with an X. The primary supplies reflect redundancy of AC inputs and backup supplies. An O indicates a slot that must have a supply because the card cage contains more than 12 cards.

In Table 3-1, the System column lists the IGX model number coupled with the number of AC inputs and whether the single-AC input models have power supply redundancy. The table also shows the slot locations A through F and the part number of the kit that contains all the pieces for the item in the System column. Extra supplies for more than 12 cards (O) are not a part of a kit under Kit Part No. but have another part number. The part number of a supply ordered to fill extra power demands is IGX-AC-PS.

Table 3-1 : Locations of Primary and Additional Supplies

System	A	B	C	D	E	F	Kit Part No.
IGX 16: 1 AC input, no power supply redundancy	X	O					IGX16-AC1-1
IGX 16: 1 AC input, with power supply redundancy	X	X	O				IGX16-AC2-1
IGX 16: 2 AC inputs	X	O		X	O		IGX16-AC2-2
IGX 32:1 AC input, no power supply redundancy	X	X	O				IGX32-AC2-1
IGX 32: 1 AC input, with power supply redundancy	X	X	X	O			IGX32-AC4-1
IGX 32: 2 AC inputs	X	X	O	X	X	O	IGX32-AC4-2

Note that, with all power supply configurations, locations for the power supplies begin at the lowest lettered slot on either side, and the occupied positions are contiguous. For example, in a dual AC system, insert a supply in A, B, D, and E.

AC Installation in a Rack-Mount Cabinet

The procedures in this section apply to both the IGX 16 and the IGX 32 in a rack. (For stand-alone systems, the power supplies are already installed.) To replace a power supply, follow the steps in the chapter titled "Repair and Replacement."

Step 1 Attach the mounting brackets to the frame. For illustrative purposes, Figure 3-7 shows mounting brackets at mid-frame and the back (using rear and mid-mount brackets is not a likely configuration). In this view of the cabinet, the rear bracket shown is labeled with a -00. Brackets on the other side of the system a -01.

Figure 3-7 : Front of Rack Mount System

Step 2 This step may require more than one person. If rear-mount brackets are used, slide in the power supply tray so its back rests on the rear bracket.

For a mid-mount rack only, attach the tray to the mounting brackets with the head of each mounting screw on the inside of the tray and each associated nut on the outside of the bracket.

Step 3 Secure the front of the power supply tray with the front screws. When tightening each of the front screws, hold the adjacent front flange of the tray slightly to the outside so the hinged door can freely open and close. See "Front Flange" in Figure 3-7. The space between the right-angle edge of the flange and the edge of the hinged door should be approximately the width of a thumbnail.

Step 4 Install the power supplies. See Figure 3-8 for an illustration of a power supply. When a power supply almost reaches the end of the slot in the tray, a slight resistance is encountered. Push the power supply slightly farther in to achieve the final position and full connector mating.

Step 5 At the front of each supply, secure the supply to the tray by tightening the captive screw at the bottom/front of the supply.

Figure 3-8 : Power Supply (viewed from front and left)

Step 6 For slots without a power supply, the hinged door has a removable, dummy panel.

Step 7 Close the hinged door and secure it with the screw at the top-center of the door. For the next step, refer to Figure 3-9, Figure 3-10, and Figure 3-11.

Step 8 Connect the power cables according to the applicable AC configuration shown in Figure 3-9. The cables in Figure 3-9 differ only in length: pinouts are identical. Attach cable 215982-01 from the far right connector---labeled A 1-16 in Figure 3-10---to the lower connector on the upper PE-BC. Figure 3-11 shows where system power connects to the PE-BC. It also shows the blank plate over an unused connection. If power supply trays D--F contain one or more supplies, run cable 215982-02 from the connector on the far left (B 1-16) to the upper connector on the PE-BC. See Figure 3-9 and Figure 3-10. For an IGX 32, run cable 215982-00 from the connector labeled 17-32 to the lower connector on the lower PE-BC.

Step 9 Attach the cable guard and tighten the captive screw at its base.

Step 10 Go to the "Installing the Cooling Unit" section.

Installing the Cooling Unit

This section describes how to install the main fan tray (Fan Tray 1) in an IGX 16 and 32 and the upper or booster fan tray (Fan Tray 2) in an IGX 32. Figure 3-12 shows the main fan tray. Figure 3-13 shows the locations of Fan Tray 1 and Fan Tray 2 in an IGX 32.

Figure 3-12 : Fan Tray Assembly

8 z

Two cables exist for supplying power to the fans. The short fan power cable is used in both the IGX 16 and the IGX 32. The long "Y" cable is used in the IGX 32 only. See Figure 3-13. In an IGX 16, the short cable connects to connector "Fan 1" of the PE-BC.

In an IGX 32, the short cable goes from the "Fan 2" connector of the upper PE-BC to the power connectors on Fan Tray 2. One branch of the Y cable for Fan Tray 1 is significantly longer than the other branch. The longer branch connects to the "Fan 1" connector of the upper PE-BC. The shorter branch connects to the "Fan 1" connector of the lower PE-BC.

To install the cooling unit assembly:

Step 1 Examine the front and back of the fan tray to be familiar with the setup. Note that, for the bottom fan tray, the captive screws that secure the fan tray are in the front. For the booster fan tray, the captive screws reside at the back of the cabinet.

Step 2 Slide in the cooling unit. and secure it by tightening the four rack screws.

Step 3 On the PE-BCs, plug each D-connector of the appropriate fan power cable into the appropriate PE-BC connector.

Step 4 Plug the power connectors into the fan trays. At the power receptacles on each fan tray, the power connector is a latched housing. Plug P1 into connector P1. Plug P2 into connector P2. Refer to Figure 3-12.

Step 5 Attach the clamp for the fan power cord to the chassis.

Step 6 For lower fan tray installation, attach the air intake bezel.

Step 7 When power is turned on, make sure all fans are running, and execute dsppwr.

Figure 3-13 : IGX 32 Back View

Readying the Cards

Before installing the cards, a step is necessary to indicate to the SCM whether the system is an IGX 16 or an IGX 32. The step consists of either removing or leaving a jumper switch on the SCM. The switch is W6. It sits above component U7P (near the top of connector P2). To indicate an IGX 32, remove the jumper. To indicate an IGX 16, leave the jumper. Make a record of this step so that checking the card later is not necessary.

Y-cable redundancy is a supported feature for many card sets. It requires an extra set of cards and a Y-cable. A set of Y-redundancy commands are also used. For instructions on setting up Y-cable redundancy, refer to the setup section for the specific card set.

Warning Connector pins must align with receptacles. Before card insertion, make sure that the pins are straight and that the connectors on the card and backplane align with each other. Insert the card gently. It may be necessary to push the edge of the card slightly to one side (this may require removing cards).

The locations of the cards depend on the hardware configuration. Except for the reserved slots, cards can reside in any slot on the appropriate side of the node. (However, StrataCom recommends that the optional ARM/ARI card set reside in slot 16.) The reserved slots are for the NPMs and SCM. The NPM can reside in front slots 1 and 2. The SCM must reside in back slot 1. Refer to Figure 3-14 for a front view of a shelf in an IGX 16 with 2 NPMs.

The NPM B versions require a minimum level of system software. Refer to the Release Note that comes with this manual to see if the software supports the NPM B version.

An IGX 32 can support a configuration of up to 16 trunk cards. This includes combined NTM and BTM card sets.
