Install the Hat Rails: 9040
The hat rails on the 9040 can be used on either side of the switch and are attached
with 4 screws. The hat rail has 8 holes: 4 correspond to the left side of the chassis
and 4 correspond to the right. When installing the hat rails, make certain that the
top of the rail is installed the same on both sides (rail is marked with "TOP") as
shown in Figure 2-11.
Figure 2-11 Installing 9040 Hat Rails
Rack-Mount the Switch
To install the switch into the rack, perform the following steps:
1. Clear the area of any unnecessary materials.
2. Attach the clip of the ESD wristband (strap) to bare metal on the cabinet. Put
the wristband around one wrist with the metal button against the skin.
3. Lift the switch and from the front of the cabinet, slide it onto the rails. The fans
and power supplies are on the front of the chassis; leaf/VIC modules are to the
rear.
CAUTION!
Never lift the switch with the handles on the spine modules, leaf modules,
power supplies, and fan trays. These handles are not designed to support
the weight of the switches.
Secure each hat section to the side of the 9040. Make
certain the top of the hat rail is installed correctly.
