3.2.3 Replacing a Disk Module
When a disk is failed by the SS8460, replace it promptly so that the operation and
performance of the system are not affected.
CAUTION : Disk spin down--Damage can occur to a disk if it is removed while still
spinning. DDN recommends that you perform ALL steps of the following
procedure to ensure that the disk has stopped prior to removal.
NOTE : Opening the cover affects the system cooling. Limit service time to
5 minutes. Reminder beeps will occur occasionally. A continuous alarm will
sound after 5 minutes.
To remove a module:
1. Ensure that the disk to be installed has acclimated to room temperature.
2. If the SS8460 is running (power on) and being used, ensure that the disk to be replaced
has no I/O activity.
3. Push in the release tabs on the enclosure front to disengage the locks. Then carefully
pull the enclosure forward out of the rack.
4. Pull the enclosure out far enough to allow the top cover to be opened. The rails will
“lock” into a service position.
5. Swing up both cover release handles to disengage the locks.
6. Lift up to open the cover.
7. Locate the disk module that has an amber Fault LED.
8. On that module, press the release latch to release the handle (Figure 50).
9. Lift handle and pull the module up, just enough to disconnect the module from the
backplane.
10. Wait for 30 seconds for the disk to completely spin down.
11. Pull the module gently out of the disk bay.
