Chapter 7 Preliminary Steps Before Installing
Installation in a non-Cisco cabinet or T-Rail type rack is similar to installation in a Cisco cabinet.
Note
Contact Cisco Customer Service for recommended rear support details.
These instructions apply to a BPX switch shelf installation in a Cisco cabinet, which has rear rails at
19.86 inches (50.5 cm) or in a customer supplied standard 19-inch (48.25 cm) equipment rack with rear
rails at a 30 inch (76.2 cm) setback.
The recommended stacking order, from the bottom, up, is:
1. BPX on the bottom
Next, the 7204 Label Switch Controller (if ordered)
2.
3. Next, the MGX (8250 or 8230) on top
Gap between the shelves is designed to be .060" minimum to allow clearance for replacement.
The first of the two following procedures is the recommended method for installing the BPX shelf and
other shelves in a Cisco cabinet: by leaving in the cards and using a lifting device to raise the fully loaded
unit into position. The second procedure describes removing all cards for situations where no lifting
device is available.
To install the fully loaded BPX switch shelf in a Cisco cabinet by means of a lifting device, use the
following procedure:
Position the shipping container and pallet facing the front of chassis. Remove the foam strips on the
Step 1
sides, front and rear.
Slide the BPX onto the lifting device platform.
Step 2
Decide where the BPX switch is to be located. The top of the spacer bracket should be temporarily
Step 3
installed in the rack 22.75" (57.8 cm.) below the location selected for the top of the BPX switch chassis.
Install the temporary support brackets and spacer bar (shipped with the unit). Use two mounting screws
Step 4
to attach each temporary support bracket and two screws to attach the temporary spacer bar to the rack.
Note
If you are installing the BPX switch shelf in a Cisco cabinet and using factory installed rear rails located
Step 5
at a 19.86 inch setback from the front, see Chapter 8, "Installation with Cisco Cabinets including
7000 Series Routers," for the installation instructions.
If you are installing the BPX switch shelf in a customer-supplied cabinet using rear rail mounting
Step 6
support brackets located at a setback of approximately 30 inches from the front, see Chapter 9,
"Installation in Customer Cabinet."
Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005
It is recommended that all BPX switches use a set of vertical support rails to provide
additional support for the rear of the chassis. In the Cisco cabinet these are located at a 19.86
inch setback from the front in factory installations.
