4-3 Troubleshooting

Power Supply

Check to see if the status indicator on the standard or redundant (if so
equipped) power supply is amber.
Figure 4-3. Power supply status indicator
If this indicator is amber, flashing amber, or alternating green/amber, replace
the power supply as soon as possible. See "Replacing Components" later in
this chapter for important information on how to replace the power supply.
Failure to observe these instructions can result in loss of data.
If the status and power indicators are both OFF on one supply of a redundant
power supply system, check the AC power source to the supply. Redundant
operation is not assured and failure to observe these instructions can result in
loss of data.
CAUTION: In a single power supply configuration, as shown in
Figure 4-3, the lower power supply cover plate must be kept in place for
thermal integrity. This is the cover plate located below the Fan array.
