Preinstallation

The SSR chassis ships secured upright in a tri-wall corrugated crate on a composite skid. The SSR ships with eighteen (18) filler modules, two (2) cooling modules, and two (2) bay controllers installed in the chassis. The SSR chassis ships with 482 mm (19 in.) mounting ears installed and 584 (23 in.) mounting ears boxed inside the crate. In addition, a route controller module cable kit ships in a box inside the shipping crate.

Additional boxes contain the installation kit and modules ordered for your chassis.

Preinstallation Tools

Rack Mounting the SSR Chassis

The SSR is mounted in a standard, zone 4 compliant, 19" or 23" rack, capable of holding at least 1000 lb. Follow the manufacturer's recommendations for installing the rack prior to mounting the SSR.

Avici recommends that the first SSR chassis be mounted in the bottom of the rack with a minimum of 48.2 mm (1.7") clearance between it and the equipment above (see Figure 2-1). The SSR can also be mounted in the top of an installed rack.

SSR chassis may also be installed in racks side-by-side. The racks must be

NOTE This is not a multi-chassis configuration. Side-by-side SSR chassis operate as independent units.

positioned on a 24" center; that is, the center of each chassis must be 24" from each other (see Figure 2-2).

Figure 2-1. Mount First SSR in Bottom of Rack

WARNING (W:2-1) The SSR installation procedures apply to the initial installation of the router. These procedures assume that you have not yet connected power to the unit.

Multiple Chassis Installations

Multi-chassis installations require that the SSR chassis be in a top and bottom position within one rack (see Figure 2-2).

For more information regarding multiple installations, see Field Replacement Procedure (FRP) 05719-00, Connecting Multiple SSR Chassis. An online version of this FRP is available at www.avici.com/documentation.

Inspecting the Shipping Contents

Remove the invoice/packing slip from the envelope on the shipping crate and check the contents of each shipping carton against the invoice.

The SSR chassis ships with the following components installed:

Route controllers, router modules, and cable kits ship separately. Installation instructions ship with each component. A box inside the crate holds a pair of 584 (23 in.) mounting ears.

NOTE Inspect the crate for damage. If the crate appears to damaged in any way, contact Customer Service. See "Support Services"" in the Preface for Avici Customer Service contact information.

Unpacking the SSR Chassis

The SSR chassis ships secured upright in a tri-wall corrugated crate on a composite skid. Partially unpack the SSR chassis before transporting it to the installation area. The chassis remains on the bottom skid until just prior to installation in a rack. While unpacking, read and comply with all shipment monitoring labels attached to the exterior of the shipping crate.

NOTE Do not remove the chassis from the skid until immediately before installing the chassis into a rack.

Step 1 Wearing protective gloves and holding down each packing strap as it is cut, use the snips to cut each strap. Dispose of cut straps (see Figure 2-3).

Figure 2-3. Unpacking the SSR Chassis

Step 2 Lift cap off the top of the crate and put aside (see Figure 2-3).

Step 3 Remove right side of crate as shown in Figure 2-4. Fold and set aside.

Moving the Chassis to the Installation Area

After partially unpacking the SSR chassis, use a standard pallet jack to transport the SSR chassis to the installation area.

CAUTION (C:2-1) Because the SSR is heavier at the rear, always position the pallet jack to the rear of the chassis.

Using a Pallet Jack

PROCEDURE: Use the following steps to secure the pallet jack to the skid and move the chassis to the installation area:

Step 1 Lower the pallet jack to just below the rear of the skid.

Step 2 Insert the pallet jack into the rear of the skid opening.

Step 3 Raise the pallet just high enough to maneuver the chassis.

Step 4 Transport the chassis to within a few feet of the installation area.

Step 5 Lower the skid and remove the jack.

Unloading the Chassis from the Skid

Use a 2-wheel lift (recommended) or other lift to install or remove the SSR from a rack.

NOTE If using a standard lift, ensure that the weight capacity of the lift is sufficient for the SSR chassis. Refer to the Table 1-1 "SSR Chassis Dimensions and Weights" for specific weight information.

For ease in lifting and moving the chassis from the pallet to the lift, use the following procedures to remove the EMI shelf cover, cooling modules, filler modules, foam shipping blocks, and front grille.

Removing the EMI Cover

Each SSR chassis ships with an Electro Magnetic Interference (EMI) shelf cover which must be removed to access SSR chassis components. The EMI cover attaches to the chassis frame via latch screws on the top and pull knobs on the bottom (see Figure 2-8 and Figure 2-9).

PROCEDURE: Use the following procedure to remove the EMI shelf cover:

Step 1 Open the hinges on the front and rear of the skid (see Figure 2-7).

Figure 2-7. Accessing the EMI Cover

Step 2 Simultaneously, pull both knobs on the bottom of the EMI cover outward from the chassis to release the bottom of the cover from the chassis (see Figure 2-8).

Figure 2-8. EMI Shelf Cover Removal - 1

Step 3 Grasp the shelf cover and rotate it upward, lifting it off the latch screws on the chassis frame (see Figure 2-9).

Step 4 Set the cover aside for reinstallation.

Figure 2-9. EMI Shelf Cover Removal - 2

Removing the Cooling Modules

The cooling modules reside on aluminum rails just above the bay controller module slots in the bottom of the chassis. Foam inserts inside the chassis protect the cooling and bay controller modules during shipment. These foam inserts must be removed before installation of the chassis.

PROCEDURE: Use the following steps to remove the front air grill to access the bay controller modules.

Step 1 Grasp the face of the front air grill firmly by the air vents.

Step 2 Pull the assembly toward the front of the chassis to release the two ball studs from the receptacles holding the assembly in place (see Figure 2-10).

Figure 2-10. Front Air Intake Grill Removal

Step 3 Grasp the foam inserts in front of the cooling modules and remove them from the chassis (see Figure 2-11).

Figure 2-11. Foam Insert Removal

Step 4 Grasp the faceplate handles with your thumb and forefinger and pull the handles towards the center to release the lock (see Figure 2-12).

Figure 2-12. Cooling Module Removal

Step 5 Carefully pull the cooling module toward the front of the chassis (a few inches) to disengage it from its slot in the rear power input panel.

Step 6 With one hand, pull the cooling module halfway out of the chassis using the handles on the front of the unit.

Step 7 Grasp the unit underneath with the opposite hand and slide it out of the chassis (see Figure 2-13).

Figure 2-13. Cooling Module Removal

Step 8 Repeat all steps to remove the remaining module.

Removing Filler Modules

The SSR chassis ships with eighteen (18) filler modules, which ensure proper cooling and elimination of electromagnetic interference during operation (see Figure 2-14).

Figure 2-14. Filler Module

PROCEDURE: Use the following steps to remove a filler module:

Step 1 Use a 1/2-in. flat-blade screw driver to loosen the lock latch on the filler module.

Step 2 Pull the filler module out of the slot (see Figure 2-15).

Step 3 Store the filler module in a safe place. You will need to replace filler modules in any unused slot.

Figure 2-15. Removing Filler Modules

Preparing for Rack Mounting

The SSR ships with two sets of 482 mm (19 in.) movable mounting ears installed on the sides of the chassis. Two sets of 584 mm (23 in.) mounting ears ship boxed inside the crate. Because each installation is unique, considerations for where and when to secure mounting ears will differ. In all installations, mounting ears must be removed before rack installation.

NOTE Front mounting is only available with a 584 mm  (23  in) rack.

After determining which set of mounting ears to use and mounting position in the rack, installation may begin.

PROCEDURE: Use the following steps to prepare the SSR chassis for rack installation:

CAUTION (C:2-2) Make sure the foam inserts (shipping blocks) have been removed from the inside front of the chassis. Foam inserts protect the bay controller modules during shipping. Operating the chassis without removing the foam inserts can cause improper air flow and equipment damage.

To remove foam inserts, see "Removing the Cooling Modules".

Step 1 Disengage the pallet jack from the skid.

Step 2 If your installation requires it, use the #2 Phillips screwdriver to remove the twelve (24) M4 flat head screws (12 per side) holding the mounting ears on the chassis prior to lifting the chassis into the rack.

WARNING (W:2-2) The SSR is heaviest at the rear of the unit. It weighs 165 lb when empty and 242 lb with shipped components. Use safe lifting procedures when moving the unit to avoid personal injury.

Step 3 Secure the chassis to the lift with the moving strap if you are moving the chassis a long distance.

Step 4 Using the installed handles on the SSR and at least three people to leverage the unit, slide the SSR off the pallet and onto the lift (see Figure 2-16).

Figure 2-16. Slide Chassis Off Skid Using Handles

Step 5 Install the twelve (12) 10-32 nut clips (or 24 if installing both mounting ears) on the mounting ears located on the chassis, or place them directly in the rack where the chassis will be mounted.

Figure 2-17. Position Mounting Ears Prior to Mounting

Rack Mounting the SSR

A 2-wheel lift is recommended for rack mounting.. For directions for removing an SSR from the skid, see "Preparing for Rack Mounting".

PROCEDURE: Use the following procedure to mount an SSR into an installed rack:

Step 1 Position the SSR, which is on a lift, to the front or rear of the installed rack.

NOTE You must remove the handles prior to placing the mounting ears onto the chassis and mounting chassis into rack.

Step 2 Using a #2 Phillips screwdriver, remove the removable handles.

WARNING (W:2-3) The SSR is heaviest at the rear of the unit. It weighs 165 lb when empty and 242 lb with shipped components. Use safe lifting procedures when moving the unit to avoid personal injury.

Step 3 Position the correct set of mounting ears on the chassis in the position most suited for your rack if your installation requires it. Use the #2 Phillips screwdriver to reinstall these same screws into the proper mounting ear location for your specific type of rack (see Figure 2-17).

Step 4 Lower the lift to the lowest point and raise the chassis by pumping the lift foot pedal to position the SSR in the rack and line up the holes in the rack mounting ears with the holes in the rack.

NOTE Be sure there is enough room to remove the lift once the chassis has been secured in the rack.

Step 5 Use the lift lock lever (if available on your lift) to lock the wheels of the lift when the SSR is in position.

Step 6 Remove the strap from the SSR chassis if one was used.

Step 7 Beginning at the bottom of the rack ears and alternating from side to side, use a 18" ratchet extension (if needed) to install the twelve (24) 10-32 panhead (panel mount) screws (12 per side) through the 10-32 nut clips and into the mounting ears on the chassis.

Step 8 After securing the chassis in the rack, unlock the wheels of the lift and carefully remove it.

NOTE Reinstall the front air grill after the SSR chassis has been mounted in a rack (see "Installing the Front Air Intake Grill").
