3.6.2 Replacing an SBB
There are two methods for replacing a disk drive SBB with an identical SBB:
•
Hot swap – This method requires that the SCSI controller support removing
and installing SBBs while the bus is active. Hot swap is supported by the
RAID Array 3000 controller
•
Cold swap – Requires removing ac power from the pedestal and disabling the
UPS to deactivate the bus
Perform the following procedure to replace an SBB in the pedestal
(see Figure 3–4):
CAUTION
•
Always use both hands when removing or in-
serting an SBB.
•
Never remove a drive from the pedestal be-
fore it has completely spun down.
•
Take care not to slam the replacement SBB
into the pedestal enclosure.
1. Unlock and open the front door.
2. Release the drive from the pedestal slot by squeezing the mounting tabs on
the SBB together, but do not remove the SBB from the pedestal.
3. Wait 15-30 seconds for the drive to stop spinning before removing it from
the pedestal slot.
4. Insert an identical model SBB in the slot and push it in until an audible click
is heard indicating the SBB is fully seated (SBB front panel mounting tabs
expand and engage the pedestal shelf).
5. Observe that the SBB status LEDs are operating.
6. Close the front door.
