Installing a PCM
Refer to
Figure 78 (page 118)
directional arrows—since you will insert the module into the slot—rather than extracting it.
IMPORTANT: Handle the PCM carefully, and avoid damaging the connector pins. Do not install the PCM if
any pins appear to be bent.
1. Check for damage, especially to all module connectors.
2. With the PCM handle in the open position, slide the module into the enclosure, taking care to support the base
and weight of the module with both hands.
3. Cam the module home by manually closing the PCM handle. You should hear a click as the latch handle
engages and secures the PCM to its connector on the back of the midplane.
4. Connect the power cable to the power source and the PCM.
5. Secure the strain relief bales.
6. Using the management interfaces (the SMC or CLI), verify whether the health of the new PCM is OK. Verify
that the green PCM OK LED is on/blinking per
no fail states. Verify that Ops panel states show no amber module faults.
7. If replacing two PCMs, repeat steps 1 through 5, being mindful of the illustrations TIP on
Replacing a drive carrier module
A disk drive module consists of a disk in a carrier or sled. Disk drive modules are hot-swappable, which means
they can be replaced without halting I/O to the disk groups, or powering off the enclosure. The new disk must be of
the same type, and possess capacity equal to or greater than the one being replaced. Otherwise, the storage system
cannot use the new disk to reconstruct the disk group.
CAUTION: Removing a disk drive module impacts the airflow and cooling ability of the enclosure. If the
internal temperature exceeds acceptable limits, the enclosure may overheat and automatically shut down or restart.
To avoid potential overheating, wait 20 seconds to allow the internal disks to stop spinning, then insert the new disk
drive module.
IMPORTANT: Familiarize yourself with FDE considerations relative to disk module installation and
replacement. See also
NOTE: When moving FDE-capable disk drive modules for a disk group, stop I/O to the disk group before
removing the disk drive modules. Import the keys for the disks so that the disk content becomes available. See the
Storage Manager Guide or CLI Reference Guide for more information.
See CAUTION bullets regarding electrostatic discharge and anti-static protection on
TIP: The illustrations show disk module replacement within the drive slots as you view the enclosure front panel.
