Installation in Customer Cabinet

This chapter provides installation steps for the mechanical placement of a BPX switch shelf in a standard 19-inch customer-supplied equipment cabinet or rack with a rear rail setback at 30 inches.

Before proceeding to this chapter, complete the procedures in:

Chapter 7, Preliminary Steps Before Installing

Installing a BPX Switch, Rear Rail Setback at 30-Inch

This procedure applies to a BPX switch shelf to be installed in a customer-supplied cabinet with rear vertical rails located at a setback of approximately 30 inches from the front.

If the BPX switch shelf is DC powered, the DC Power Entry Modules are factory-installed in the lower portion of the rear of the BPX switch shelf itself. Locate the DC Power Entry Module(s) and make sure it/they are equipped as ordered.

If the BPX switch shelf is AC powered, you will also need to install an AC Power Assembly below it.

Preliminary Procedure:

Proceed as follows to install the BPX switch shelf, referring to Figure 9-1 through Figure 9-3, and to either Figure 9-4 for DC-powered systems or Figure 9-5 for AC-powered systems. Figure 9-2 shows the location of the rear-located third rails in a customer supplied cabinet and of the corresponding adjustable plates and support brackets on the BPX switch shelf.

Step 1 With one person on each side of the BPX switch shelf, lift the pallet tray and BPX switch shelf positioning the slots at the rear of the pallet tray over the locating tabs on the spacer bracket (see Figure 9-1).

Step 2 Slide the BPX switch shelf back over the support brackets and into place.

Step 3 Secure the BPX switch shelf to the front rail using 8 each #10-32 screws.

Note European installations may use a size M6 metric screw.

Step 4 Locate the two rear support brackets and adjustable plates in the miscellaneous parts kit.

Step 5 Position the adjustable plates with the tabs in the three punchouts facing up as shown in Figure 9-3.

Step 6 Align the top and bottom holes in the adjustable plates with corresponding holes in the side panel of the BPX switch shelf. (The bottom of the plates should be approximately aligned with the bottom of a DC- powered BPX switch shelf. They should be extended below the bottom of an AC-powered BPX switch shelf so that the AC Power Supplies can be secured to the shelf.)

Step 7 Secure one each adjustable plate to each side of the BPX switch shelf, using (2) each #10-32 machine screws and flat washers.

Step 8 Attach a rear support bracket to each one of the adjustable plates with 2 each #10-32 screws and washers. Do not tighten yet.

Step 9 Secure the support brackets to the rear located vertical rails using 2 each #10-32 screws. You might have to lift the BPX switch shelf slightly to align the holes in the bracket to the holes in the rack.

Step 10 Tighten the screws attaching the support bracket to the adjustable plate.

Step 11 Slide a cable strap over each of the three tabs on the support brackets.

Step 12 Remove the temporary support bracket and spacer bracket from the front of the cabinet.

Step 13 If this is a DC-powered shelf, proceed to Chapter 10, Installing the DC Shelf.

Step 14 If this is an AC-powered shelf, proceed to Chapter 11, Installing the AC Shelf.
