Checking the Indicator Lights

007-4834-001 35

The normal operating state of all indicators on the rear panel is green. If an amber

indicator is on, or a green indicator is off, use TPSSM to determine the nature of the fault

and the recovery procedure.

There is a link rate switch to the right of the front indicator lights and alarm mute

button. The link rate lights are located on the back of the drive tray. The link rate switch

(see Figure 3-4) enables you to select the data transfer rate between the ESMs and the

drives to either 2 Gb/s or 4 Gb/s. The link rate switch is only read when power to the

drive tray is turned on. Callout 1 in Figure 3-4 shows the location of the switch.

Callout 1 in Figure 3-5 shows a blowup of the location of the link rate LEDs (on the back

of the enclosure). When the storage enclosure is operating at 2 Gb per second only one of

the LEDs is on. When it is operating at 4 Gb per second both LEDs are lit.
