Installation and User's Guide

Installing and replacing devices

This chapter provides instructions for installing or replacing customer replaceable units (CRUs), such as hot-swap drives, ESM boards, the bridge card, the switch card, and power supplies.

Attention: If you have data stored on the drives, label the drives before you remove them. Then, when you replace the drives, install each one in the same drive bay from which you removed it. Failure to do so could result in a loss of data.

Attention: Static electricity, though harmless to you, can seriously damage storage unit components or options. See Handling electrostatic discharge-sensitive devices for details.

Attention:

It is easier to lift the storage unit if you remove all CRUs (disk drives, power supplies, and ESMs) first. A fully loaded storage unit with 14 hard disk drives and two power supplies installed weighs 36.1 kg (79.5 lb). The standard unit with two power supplies weighs 22.5 kg (49.5 lb). If you remove all the CRUs, you can reduce the overall weight.

>=18 kg (37 lb)	>=32 kg (70.5 lb)	>=55 kg (121.2 lb)
Caution: Use safe practices when lifting.
