Four Post Procedure
To mount the switch on four posts in a rack using the provided mounting kit:
1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2. Decide whether the Field Replaceable Unit (FRU) end of the switch or the port end is
to be placed at the front of the rack. Position the switch in such a manner that the AIR
IN labels on components are next to the cold aisle and AIR OUT labels on components
are next to the hot aisle.
3. Align the holes in the mounting rail with the holes on the side of the chassis. See
Figure 18 on page 143 to see the proper alignment for the EX4600 switch.
