4-2 620J Storage Enclosure Installation and Overview Guide

While power is being applied to the storage enclosures, the LEDs on the front and

the rear of the storage enclosures turn on and turn off intermittently.

The storage enclosures might take several minutes to turn on completely. Wait until

the storage enclosures are completely turned on before turning on the power to

the host.

Steps to Check for Problems – Storage Enclosure

Refer to the following figures for the location of the LEDs on the canisters:

• Figure 4–2, “LEDs on the Left End Cap” on page 4-3

• Figure 4–3, “LEDs on the Drive” on page 4-4

• Figure 4–4, “LEDs on the ESM Canister” on page 4-5

• Figure 4–5, “LEDs on the Power-Fan Canister“ on page 4-7

The LEDs let you know that your hardware devices are fully operational or whether a

fault condition exists.

1 Make sure that all of the LEDs show normal operation. See “LEDs on the Storage

Enclosure” on page 4-3 for a description of the LEDs on the storage enclosure.

2 Do you see any amber LEDs on the storage enclosure?

NOTE The ESM links have four PHYs. As long as any one PHY is operational, the

green ESM Link LED comes on. If any one PHY becomes nonoperational,

the amber ESM Link Fault LED comes on. It is possible for both the ESM

Link LED and the ESM Link Fault LED to be on at the same time.
