Verifying prope

roperation

After replacing

the failed SFP, verify that:

• The 1-Gb and 2-Gb link-status LEDs on the Fibre Channel I/O module cycle through blinking amber

and green and then Off to indicate that the circuitry has recognized a newly installed SFP.

• The status LED on the Fibre Channel I/O module is solid green.

• No new error mes

sages are displayed on the array controller LCD panel.

Replacing a power supply/fan assembly

The assembly is hot-pluggable, so it is not necessary to power down the system to replace it.

Before you begin

CAUTION:

• Before removing a component or blanking panel from an operational device, make sure that you

have the replacement part available. Removing a component or blank impacts the airﬂow and

cooling ability of the device. To avoid possible overheating, insert the new or replacement component

withinoneortwominutes. Iftheinternaltemperatureexceedsacceptablelimits,thedevicemay

overheat and automatically shut down or restart.

• Parts can b

e damaged by electrostatic discharge. Use proper anti-static protection.

CAUTION:

• Replacement power supply assemblies do not include a variable speed fan. You must remove the

operational fan from the defective power supply and install the fan on the new power supply.

• The fan blades rotate at a high speed and do not stop immediately when power is removed from

the MSA. Allow time for the blades to stop rotating. Avoid touching the rotating blades when

removing the fan.

• The fan shell must be handled carefully to avoid breaking it. Do not press on the center section of the

fan shell (circular panel covering the blades). To avoid damaging the fan blades, grasp only the

outer portion of the fan shell. Do not rest the power supply on the fan. Doing so might break the fan.

Verifying component failure

• Check t

he array controller LCD display panel for error messages.

• Verify that the electrical source is delivering power down the AC power cord.

• Verify that the power supply fault LED is ﬂashing amber.

• Verif

y that the power supply Power on/off LED is Off.

Removing the component

1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions.

2. Disengage the cord lock and disconnect the AC power cord from the failed power supply.

CAUTION:

When removing the left power supply, move the cord lock on the right power supply out of

the way to avoid dislodging the right power supply and causing your system to become

overheated.
