Preinstallation

The SSR chassis is delivered to your receiving dock secured upright on a shipping pallet inside a wooden crate. Protective packaging covers the entire chassis. Additional boxes contain the modules ordered for your chassis and the cables needed to interconnect router and route controller modules.

Preparing for installation involves the following procedures:

Required Tools

Depending on your rack type, you may also need the following tools:

Inspecting the Shipping Contents

The SSR chassis ships with cooling modules, bay controller modules, and filler modules installed.

All route controller modules, fabric filler modules, and router modules are shipped separately. Installation instructions ship with each module.

When you receive your SSR, inspect the shipping contents as described next.

PROCEDURE: Use the following procedure to inspect the shipping contents:

Step 1 Remove the invoice/packing slip from the envelope on the shipping crate.

  1. Check the contents of each carton against the invoice. Do not open the crate at this point. Wait until you move the crate to the installation site and unpack the chassis to inspect crate contents.

  2. If any parts are missing or there is evidence of physical damage, contact your sales representative immediately.

    Step 2 Inspect the exterior of the crate for damage.

Moving the Chassis to the Installation Area

Following the instructions given next, use a standard pallet jack to transport the QSR crate to the installation site.

NOTE Before unpacking the QSR, transport it to the installation site.

PROCEDURE: Use the following steps to move the crate to the installation area:

Step 1 Lower the pallet jack to just below the crate.

Step 2 Slide the pallet jack forks under the crate.

Step 3 Raise the crate just enough to maneuver it.

Step 4 Transport the crate to within a few feet of the installation site.

Step 5 Lower the crate and remove the pallet jack.

Unpacking the QSR

PROCEDURE: Use the following steps to unpack the QSR:

Step 1 Read and comply with all shipment monitoring labels attached to the exterior of the shipping crate.

Step 2 Locate the four spring-loaded twist latches and four klimps on the crate. Two latches secure each side of the crate and two klimps secure each end.

Figure 2-1. Locating the Twist Latches

Step 3 Unlock the latches as follows:

    1. Pull the handle down until it sits at a right angle to the crate.

Figure 2-2. Positioning the Handle
    1. Turn the handle clockwise until it stops to release the latch.

Figure 2-3. Releasing the Latch
    1. Lift the entire latch assembly up and away from the crate.

Figure 2-4. Lifting the Latch Assembly

Step 4 Use the large flat-head screwdriver to pry off the metal klimps from the front and back of the crate.

Step 5 With a person at both ends of the crate, lift the hood straight up and off the base (see Figure 2-5) and set it aside.

CAUTION (C:2-1) While removing the hood, be sure to completely clear the inner packing containing the QSR before setting the hood aside.

Figure 2-5. Removing the Hood

Step 6 Remove the restraining strap that secures the inside top support and lift the support up and off the unit (see Figure 2-6).

Figure 2-6. Removing the Inner Top Support

Step 7 Remove the plastic wrap from the chassis.

NOTE The chassis ships with only five filler modules installed. The remaining slots are empty.

Step 8 Inspect the chassis for missing parts and damage.

Preparing to Remove the Chassis from the Pallet

Lifting the chassis from the pallet requires two people. When installing the chassis in a rack, a third person to guide and secure the chassis during mounting can prove helpful.

WARNING (W:2-1) The back of the QSR is the heaviest part of the unit. The chassis weighs 132 lb (59.87 kg) with shipped components. Use safe lifting procedures when moving the unit to avoid personal injury.

You can eliminate some weight from the chassis to ease lifting by removing the filler modules.

Removing the EMI Cover

Each QSR chassis ships with an Electro Magnetic Interference (EMI) cover installed. It is necessary to remove the EMI cover to access QSR components.

The EMI cover attaches to the frame via latch screws on the top and release knobs bottom right and left of the cover (see Figure 2-7 and Figure 2-8).

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

Step 1 Pull the release knobs on the bottom left and right of the cover away from the chassis to release the bottom of the EMI cover (see Figure 2-7).

Figure 2-7. QSR EMI Cover Removal - 1

Step 2 Grasp the shelf cover and rotate it upward, lifting it off the latch screws on the chassis frame (see Figure 2-8).

Step 3 Set the cover aside for later reinstallation.

Figure 2-8. QSR EMI Cover Removal - 2

Removing Filler Modules

The QSR ships with 5 filler modules installed. During QSR operation, filler modules installed in the appropriate unused slots ensure proper cooling and eliminate electromagnetic interference.

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

Step 1 Using a 1/2-in. flat-head screwdriver, turn the latch screws that secure the filler module to the chassis (see Figure 2-9).

Figure 2-9. Locating Filler Module Latch Screws

Step 2 Pull the filler module out of the slot (see Figure 2-10).

Figure 2-10. Removing Filler Modules

Step 3 Store the filler modules in a safe place for future use.

Attaching the Mounting Handles

In order to mount the handles onto the QSR, remove the faceplate. The faceplate attaches to the QSR with ball studs (see Figure 2-11).

PROCEDURE: Use the following procedure to attach the mounting handles to the QSR:

Step 1 Hold the faceplate by the edges and pull it away from the chassis (see Figure 2-11). The ball studs release the faceplate from the QSR.

Figure 2-11. Removing the QSR Faceplate

Step 2 Locate the two mounting handles that ship with the QSR and remove them from the packing material.

Step 3 Align the three screws each handle with holes on the front and the back of the chassis. See Figure 2-12.

Figure 2-12. Attaching the Mounting Handles

Step 4 Tighten the screws to secure both handles to the QSR.

Step 5 Using the mounting handles, lift the QSR out of the crate and onto the floor in front of the rack.

Step 6 Continue to the next section, "Rack Mounting the QSR."

Rack Mounting the QSR

Decide on the position in the rack where you plan to install the QSR. If installing the QSR in an empty rack, always install the first chassis in the bottom of the rack. QSR supports installation for front, rear, or mid-mounting.

Lifting the chassis from the pallet requires two people. When installing the chassis in a rack, a third person to help guide and secure the chassis during mounting can prove helpful.

WARNING (W:2-2) Use safe lifting procedures when lifting and moving the unit to avoid personal injury.

NOTE The QSR must be mounted in a standard, zone 4 compliant, 19-inch or 23-inch rack, capable of holding at least 1000 lb. Follow the manufacturer's recommendations to set up the rack prior to mounting the QSR.

You can rack mount the QSR from the front or rear. If the rack is a 19" rack, the QSR can be mounted from the rear only. Before rear mounting, remove the mounting ears located in the middle of the chassis and move them to the required position.

Leave a clearance of 1.575 mm (.062 in.) between the top of the QSR and equipment being installed above the QSR. To rack mount a QSR

Figure 2-13 shows two rack-mounted QSRs.

Figure 2-13. Mounting QSRs in the Rack

For instructions on connecting two or more QSRs, refer to the Field Replacement Procedure (FRP), "Connecting Multiple Chassis."

WARNING (W:2-3) This procedure requires two people to lift the QSR from the shipping crate. A third person to guide the QSR into the rack and tighten the screws to secure the chassis may prove helpful.

Mounting the QSR in the Bottom of a Rack

Determine if you are front, mid, or rear mounting the QSR. If you are front mounting the QSR, remove the second set of mounting ears. If the rack is a 19" rack, the QSR can be mounted from the rear only. If you are rear mounting the QSR, remove the mounting ears from the front and middle of the chassis to the required position.

PROCEDURE: Use the following procedure to mount the QSR in a secured rack:

Step 1 Using the mounting handles, slide the QSR through the front of the rack, to the required position.

Step 2 Align the holes in the mounting ears with the holes in the rack. If you are middle or rear mounting, align the respective holes.

Step 3 Beginning at the bottom of the mounting ears and alternating from side to side, secure eight #10 panhead (panel mount) screws (four per side) through the mounting ears to the rack.

Step 4 Loosen the three screws from each mounting handle and remove the handles from the QSR. Store the handles in a safe place for future use.

Step 5 Replace the QSR faceplate as described in "Replacing the Faceplate".

Mounting the QSR above Another Chassis

If you rack mount the QSR above another chassis, follow the space requirements for the chassis over which the QSR will be installed. For example, if mounting the QSR above another QSR, leave 1.575 mm (.062 in.) between them.

Determine if you are front, mid, or rear mounting the QSR. If you are front mounting the QSR, remove the second set of mounting ears. If you are rear mounting the QSR, move the mounting ears from the middle of the chassis to the rear.

PROCEDURE: Use the following steps to mount the QSR above another chassis.

Step 1 Locate the four mounting braces that ship with the chassis.

Step 2 Determine how much space to leave between the QSR and the chassis below it.

Step 3 Align a brace with the holes on the rack mounting ears leaving the required space and secure the brace to the rack.

Step 4 Align each of the other braces with the first brace and the holes on the rack, and secure the braces to the rack (see Figure 2-14).

Figure 2-14. Attaching the Braces

Step 5 Once the four braces are attached to the rack, visually check that the braces align properly to form a level, even plane on which to rest the QSR.

While you secure the QSR in the rack, the braces hold the chassis to allow you to maneuver.

CAUTION (C:2-2) If the braces do not align properly, the QSR could tip or become unstable during installation.

Step 6 Using the mounting handles, lift and slide the QSR into the rack just above the braces.

Step 7 Rest the QSR on the braces.

Step 8 Align the holes in the QSR mounting ears with the holes in the rack.

Step 9 Beginning at the bottom of the mounting ears and alternating from side to side, secure eight #10 panhead (panel mount) screws (four per side) through the mounting ears to the rack.

After securing the chassis to the rack, you may leave the braces attached to the rack or remove them. They are no longer required.

Step 10 Loosen the three screws from each mounting handle and remove the handles from the QSR. Store the handles in a safe place for future use.

Step 11 Replace the QSR faceplate as described in "Replacing the Faceplate.

Replacing the Faceplate

PROCEDURE: Use the following steps to replace the QSR faceplate:

Step 1 Align the QSR faceplate with the front of the chassis and press it until the ball studs engage and it snaps into place (see Figure 2-15).
