Installing The Switch Into A 2-Post Rack - IBM SAN48C-6 Installation, Service And User Manual

8. Holding the switch with both hands, position the two rack-mount guides on the switch between the
rack or cabinet posts that do not have slider rails attached to them.
9. If you have attached a grounding wire to the chassis grounding pad, connect the other end of the wire
to the facility ground.

Installing the Switch into a 2-Post Rack

Before you begin
If your switch must meet NEBS standards, ensure that it is configured to be compliant. For more
information, see the NEBS Compliance section.
Determine how you want to set up your switch:
Procedure
1. Determine which end of the chassis is to be located in the cold aisle.
• If the switch has port-side intake modules (fan modules and power supply units with red coloring),
position the switch so that its ports are in the cold aisle.
• f the switch has port-side exhaust modules (fan modules and power supply units with blue coloring),
position the switch so that its fan modules and power supply units are in the cold aisle
2. Determine which way the chassis should slide in and out of the rack—port side entry first or rear-side
entry first. You might consider whether the front or back of the rack provides better clearance for
maneuvering the chassis in and out during installation and servicing. The end that needs to enter the
rack first requires the guides and the other end the brackets.
3. Install two rack–mount brackets onto the switch as follows:
a) Position a rack-mount bracket so that four of its screw holes are aligned to the screw holes on the
side of the chassis. You can align any four of the holes in the rack-mount bracket to four of the six
screw holes on the side of the chassis. The holes that you use depend on the requirements of your
rack and the amount of clearance. For more information on clearance, see the "General
Requirements for Cabinets and Racks" on page 9.
b) You can install the rack-mount bracket either at the front or rear of the chassis. The choice is
determined by which end of the chassis will be inserted into the rack first. If the rear end of the
chassis is to be inserted first, then mount the brackets on the front of the chassis. If the front end of
the chassis is to be inserted first, then mount the brackets on the rear of the chassis.
