2. Grasp the handles of the fan module with both hands and pull it outward to
3. Pull the fan module fully out of the chassis.

Starting Up the Switch

This section provides the following information:

Note: Hazardous voltage or energy is present on the backplane when the system is
operating. Use caution when servicing.
CAUTION:
During this procedure, wear grounding wrist straps to avoid ESD damage to the
switch.
Note: The 3000-W power supplies provide power according to the input voltage. If
they are in redundant rather than combined mode at 110 VAC, they may be unable
to provide adequate power to all modules present in the system. See Appendix A,
"Product Specifications," on page 99.

Verifying Component Installation

About this task
Note: Blank faceplates and cover panels serve three important functions: they
prevent exposure to hazardous voltages and currents inside the chassis; they
contain electromagnetic interference (EMI) that might disrupt other equipment; and
they direct the flow of cooling air through the chassis. Do not operate the system
unless all cards, faceplates, front covers, and rear covers are in place.
Gently push the fan module into the chassis and the guide pin will self-align to
the top and bottom chassis matching slots. After fully engaged, tighten the
captive screws to 5 in-lb to secure fan module to chassis. The fan module will
just snap in.
them operating. If you do not hear them, ensure that the fan module is inserted
completely in the chassis and the outside surface of the fan module is flush
with the outside surface of the chassis.
fans are faulty. If this occurs, contact your customer service representative for a
replacement part.
unseat the power connector from the backplane.
