6–2 Enclosure 4200 Family LVD Disk Enclosures User Guide

ESD Protection

When you replace a CRU, you must take precautions to prevent the possibility of electrostatic discharge (ESD) damaging sensitive electronic items.

1.Always transport and store CRUs in a static-safe container.

2.Do not remove the CRU from the static-free container until you are ready to install it.

3.Avoid touching the CRU connector pins, leads, or circuitry.

Basic Replacement Procedures

The procedures in Table 6–1 apply to all the CRU replacement procedures.

CAUTION: The hot-pluggable power supplies, fans, EMU, and drives do not require quiescing the SCSI bus, that is halting all data transfers, the SCSI bus.

Replacing an I/O module or a SCSI bus cable always requires quiescing the SCSI bus.

Table 6–1 Common Replacement Procedures

1.Always transport and store CRUs in a static-safe container.

Before starting the replacement procedure

CAUTION: To prevent ESD damage, never touch the CRU connector pins, leads, or circuitry.

2.Remove the defective CRU from the enclosure.

3.Remove the replacement CRU from the static safe container and verify that it is a compatible replacement (refer to Figure 6–1).

4.Align the CRU with the enclosure guide slots.

5.Slide the CRU into the enclosure until it is against the backplane connector.

6.Fully seat the CRU in the enclosure and verify that if operating properly.
