2 With the physical disk carrier handle open, carefully align the channel on the disk carrier guide rail
with the appropriate disk slot keying feature on the chassis face plate, and insert the disk (see
Figure 4-2).
3 Push the physical disk carrier into the slot until the bottom of the open carrier handle makes contact
with the chassis face plate.
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 72.
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 4-4).
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.
