Installing The Router Chassis In The Rack - Cisco ASR 903 Installing Manual

Installing the Cisco ASR 903 Router
The A903-FAN-E fan tray with filter (A903-FAN-F) cannot be mounted using the mounting screws that are supported
for A903-FAN fan tray. This is not an issue with the FAN tray filter blank panel (A903-FAN-F-B). We recommend that
you use the short screws provided in the following rack mount kits to avoid interference of the air filter during rack
mounting and while replacing the fan tray (A903-FAN) with the fan tray (A903-FAN-E):
• 19" rack mount kit (A903-RCKMT-19IN)
• ETSI rack mount kit (A903-RCKMT-ETSI)
What to Do Next
Repeat Step 2 and Step 3 for the other bracket.

Installing the Router Chassis in the Rack

The procedures in this section apply to both horizontal and vertical mounting of the router in a rack.
To install the router chassis in the equipment rack, perform these steps:
Step 1 Position the chassis in the rack as follows:
• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between the mounting
posts.
• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting posts.
Step 2
Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment rack.
