Installing Enclosure Components
4 Rotate the carrier handle to the closed position while continuing to push
the carrier into the slot.
The status LED indicator (see Table 1-3 for description) will display a
steady green if the physical disk is inserted properly. If the indicator is not
illuminated, see "Troubleshooting SAS Physical Disks" on page 76.
NOTE:
At least two physical disks must be installed in the enclosure.
Removing and Installing a RAID Controller
Module
The enclosure contains two RAID controller modules. Both are hot-pluggable
and can be removed and installed independently without shutting down the
enclosure.
NOTICE:
Removing a module is not recommended while data traffic involving that
module is occurring. Although RAID controller modules are hot-pluggable, data loss
could result from removing a module involved in data traffic.
CAUTION:
Always wear a wrist grounding strap when handling equipment with
static-sensitive components. See your Product Information Guide for safety
information.
Removing a RAID Controller Module
1 Push up on the release tab on the left side of the module (see Figure 3-4).
2 At the same time, pull out on the release lever. When the lever is pulled
out, the controller module partially ejects from the enclosure.
3 Remove the module from the enclosure and place it on a flat, secure
surface.
NOTICE:
To avoid damage to the sensitive EMI contacts on the bottom of the
controller module, do not stack or place it on a hard surface.
