Table 9 O/S disk activity and status LEDs
LEDs
Meaning
Blue
If this LED is on and blue, the disk is operating normally and no
problems have been detected. If the LED is flashing blue, it indicates
disk activity. If the LED is on, but not flashing, there is currently no
disk activity.
Red
If this LED is on immediately after installing a new O/S disk, it
indicates that the RAID configuration for the server is being rebuilt.
The LED will turn off after the RAID configuration is restored. The
amount of time it takes for the RAID configuration to be rebuilt after a
new disk drive is installed depends on the amount of user and system
configuration data stored.
If this LED is on during the course of normal operation (not after
installing a new O/S disk), either the disk has failed or the server’s
RAID configuration has been degraded.
Fans
The server features dual hot-swappable fan assemblies. The fans provide for front-to-
back airflow to be consistent with other storage system components.
