Removing the Chassis
This section contains the following procedures:
• Removing the Chassis from a Tabletop or Flat Surface, page 6-74
• Removing the Chassis from the Equipment Rack, page 6-74

Removing the Chassis from a Tabletop or Flat Surface

Because of the weight and awkwardness of lifting and supporting the chassis, you
will need two persons to remove the chassis from a tabletop or other flat surface
safely. Each person should review and observe the safe lifting guidelines in the
“Lifting Guidelines” section on page 2-5 before attempting to remove the chassis.
To remove the defective chassis from a tabletop or flat surface, follow these steps:
Step 1 Ensure that all cables are disconnected and moved out of the way.
Step 2 With one person positioned on each side of the chassis to lift the weight of the
chassis and hold it steady, move the chassis off of the tabletop or flat surface and
carry it to the place prepared to store the defective chassis temporarily after it is
removed.
Step 3 Set the chassis safely aside.

Removing the Chassis from the Equipment Rack

Before you remove the defective chassis from the equipment rack, examine how
the chassis is mounted in the rack:
• Mounted directly against the rack flanges, but sitting on the optional
rack-mounting brackets (see Figure 3-1 on page 3-4)
