FRU Removal and Replacement

229Director 2/64 Service Manual

Remove and Replace FRUs

This section describes procedures to remove and replace director FRUs, along

with a list of tools required to perform each procedure. In addition, the section

provides:

■ ESD information.

■ A list of concurrent FRUs. Concurrent FRUs can be removed and replaced

while the director is powered on and operational.

■ A list of non-concurrent FRUs. Non-concurrent FRUs can only be removed

and replaced after the director is powered off.

See “Illustrated Parts Breakdown” on page 265 for FRU locations and part

numbers.

ESD Information

When performing procedures described in this section, follow all ESD

procedures, WARNING statements, and CAUTION statements.

Caution: To avoid causing machine errors or damage while working on the

director, follow ESD procedures by connecting a grounding cable to the

director chassis and wearing an ESD wrist strap.

The ESD grounding point for the front of the chassis (1) is located at the bottom

center, adjacent to the left power supply, as shown in Figure 72. Touch the chassis

once before performing any maintenance action, and once each minute while

removing or replacing FRUs.

If the director is not connected to facility power (and therefore not grounded),

connect the ESD wrist strap to an approved bench grounding point instead of the

chassis.
