FRU Removal and Replacement
3. After completing the steps of a detailed procedure that is referenced from another
procedure, return to the initial (referencing) procedure and continue to the next
step of that procedure.
4. After completing a replacement procedure, clear the event code reporting the
failure and the event code reporting the recovery from the Director 2/64 Event Log

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 nonconcurrent FRUs. Nonconcurrent FRUs can only be removed and
replaced after the director is powered off.
See Chapter 5, Illustrated Parts Breakdown for FRU locations and part numbers.
ESD Information
When performing procedures described in this section, follow all ESD procedures,
WARNING statements, and CAUTION statements. When removing and replacing
FRUs, always connect a grounding cable to the director chassis and wear an ESD wrist
strap.
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 4–1. 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.
