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 points for the front of the chassis ( 1 ) are located at the right
and left sides of the chassis, 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. The ESD grounding point for the rear of the chassis (
1 ) is
located next to the maintenance port, as shown in Figure 72 . Touch the chassis
once before performing any maintenance action, and once each minute while
removing or replacing FRUs.
