Extract the RAID controllers or expansion controllers from the back of the
original disk array and slot them, in the same order, into the new disk array.
Installing the Disk Array Chassis
Prior to replacing the disk array chassis, you MUST power down the probe. See the Power
Down Procedure for details on powering down the probe.
Identify which disk array is being replaced (Controller 0, Controller 1, or an Expansion Disk
array {JBOD}).
If you are replacing both controllers, special commands must be performed before and after
hardware replacement. Contact Tektronix Communications Customer Support for
assistance.
Verify that all cables, terminating at the disk array, are properly labeled. Record the cable
connections, for use when reconnecting the cables.
Be sure to review Storage Array Maintenance Guidelines before proceeding to ensure
component compatibility.
Step Action
1. Using two people, slide the disk array into the brackets in the same position as
the original disk array chassis and secure the new disk array chassis using the
same screws from the original disk array.
2. Reconnect the power, Ethernet, and SAS
cables
according to what was
recorded previously. For detailed cabling information, see the cabling section of
the installation guide for your specific probe type and configuration.
3. Restore power:
DC: Connect the power cables to the PSUs.
- Tighten the cable-locking screws attaching the connectors to the PSUs.
- O
pen the main circuit breakers to the power supply units.
AC: Plug in the AC cables to the power supply units.
4. Power up the new disk array. Press the power switch, on both power supply
unit
s, to the ON position. (Figure 5.55)
