IBM 8265 Nways ATM Switch, Installation Manual

Page: 27 / 102

Pre-installation Guidelines
Before mounting the 8265 in a rack:
1. First make sure the selected rack can support at least three times the weight of a fully- loaded switch.
2. Bolt the rack to the floor.
3. Brace the top of the rack to the wall.
4. Ensure that there is sufficient vertical space in your rack for each 8265 you wish to install.
5. Install patch panels in the rack for easier cable management.
6. Rack mount flanges are set to flush mount at the factory. If desired, change the rack mount flange
position by removing the screws that attach each flange to the switch. When re-installing the rack
mount flanges on the switch, make sure both flanges are set to the same position before you re-install
the screws. Also, make certain that all removed screws are re-installed correctly.
7. When installing the switch, continue to support the weight of the switch until after you have installed
four of the eight screws (two screws per rack mount flange). Install the four remaining screws to fully
secure both rack mount flanges to the rack.

8. Install the Cable Management Tray beneath the switch. The tray is designed to manage the cables
attached to the front of the switch by feeding them under and through the back of the unit. Use of the
cable tray is optional. You can mount the cable tray onto the rack in one of four positions. Mount the
switch using the same rack mount position settings as those used to mount the cable tray.
