172 QXS G2 Hardware Installation and Maintenance Guide
Installing a 2U PSU
on page 171 when performing this procedure, but
ignore the directional arrows—since you will insert the module into the slot—rather than extracting it
from the chassis.
IMPORTANT:
Handle the PSU carefully, and avoid damaging the connector pins. Do not install the
PSU if any pins appear to be bent.
1
Check for damage, especially to all PSU connectors.
2
With the PSU handle in the open position, slide the module into the chassis, taking care to
support the base and weight of the module with both hands.
3
Lock the module into its slot by manually closing the PSU handle.
You should hear a click as the latch handle engages and secures the PSU to its connector on the
back of the midplane.
4
Connect the power cable to the power source and the PSU.
5
Secure the strain relief bales.
6
Using the management interfaces (the disk management utility (GUI) or CLI), verify whether the
health of the new PSU is OK.
a
Verify that the green PSU OK LED is on/blinking.
b
Verify that cooling fans are spinning with no fail states.
c
Verify that Ops panel states show no amber module faults.
7
If replacing two PSUs, repeat steps 1 through 5, being mindful of the tips for

Replacing a 2U Drive Carrier Module
CAUTION:
Always set up global spare drives to ensure that if a disk group fails, it can rebuild. Refer
to the
QXS G2 Disk Management Utility User Guide
, Managing Global Spares.
A disk drive module consists of a drive in a carrier or sled. Drive modules are hot-swappable, which
means they can be replaced without halting I/O to the disk groups, or powering off the chassis. The
new drive 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 drive to reconstruct the disk group.
CAUTION:
Removing a drive module impacts the airflow and cooling ability of the chassis. If the
internal temperature exceeds acceptable limits, the chassis may overheat and automatically shut
down or restart. To avoid potential overheating, wait 20 seconds to allow the internal drives to stop
spinning, then insert the new drive module.
IMPORTANT:
Familiarize yourself with FDE considerations relative to disk module installation and
replacement. See also
