Precautions
If you remove a PCI module during operation, dual configuration of its internal hard disks
will be cancelled. If you mount the module again, the dual configuration will be restored
automatically. However, do not perform a system shutdown or remove any of the PCI
modules before the dual configuration is completed. Otherwise, hard disk data could be
corrupted.
Removing the primary (active) module will cause unexpected trouble. Be sure to remove
the secondary (inactive) module.
When the secondary BMC is not in synchronous condition, removing the PCI module on
the primary BMC will lose the SG data (system data). If one of the STATUS LEDs is
blinking in red, do not remove the PCI module associated with another STATUS LED.
When DC power is off:
BMC#1 BMC#2 Status
Off (Primary)
Blinking in red
(Secondary)
(At 1-second intervals)
Do not remove the PCI module on Primary
BMC side.
BMC Sync disabled.
Off (Primary)
Illuminates red
(Secondary)
Do not remove either PCI modules.
During BMC DUMP.
Off (Primary)
Blinking in red
(Secondary)
(At 0.5-second intervals)
Do not remove either of the PCI modules or
control the AC/DC power before the LED
stops blinking.
When DC power is on:
BMC#1 BMC#2 Status
Blinking in

Do not remove the PCI module on Primary
BMC side.
BMC Sync disabled.

During BMC Sync.
Blinking in

(Primary)

Blinking in red

Do not remove either of the PCI modules or
control the AC/DC power before the LED
stops blinking.
When you remove a PCI module, the system will be powered off automatically. If there is
a CD-ROM in the drive, eject it before removing the module.
When you insert a PCI module while the system is off, make sure that the newly inserted
PCI module’s BMC status lamp is off and then press the power switch.
When replacing a PCI module and a CPU module, replace one module and wait until dual
configuration is established to replace the other module. If you replace the both modules
simultaneously, dual configuration of either CPU modules or PCI modules may fail. (See
