Figure 25. Attaching the Brackets to Install the Switch in an Equipment
Rack (Continued)
The AT-8100L/8, AT-8100L/8POE, AT-8100L/8POE-E, and AT-8100S/
24C Switches come with one short bracket and one long bracket.
Allied Telesis recommends installing the short bracket on the right side
and the long bracket on the left side, as you face the front of the unit,
so that the stacking ports on the unit align with the same ports on other
8100L and 8100S Switches in the equipment rack. The possible
positions of the brackets are shown in Figure 26 on page 74 and
Figure 27 on page 75.
