Pre-installation Guidelines
Before installing the cable management tray in a rack, determine which cable management tray rack
mount position is best for you by examining the following:
Ÿ
Location in the rack where the switch will be installed (refer to “Pre-installation Guidelines” on
page 13).
Ÿ
Depth of the rack in to which the switch will be installed.
Ÿ
Space required for ventilation. A minimum of 15 cm (6 in.) is required between the rear of the 8265
and the nearest wall or vertical surface.
Ÿ
Room required for module cables to bend.
Ÿ
Proximity of other devices in the rack and their installation or environmental requirements.
