Replacing the Loop Bypass Board (LBB) or
RAID Controller
Use the following instructions to replace an LBB or RAID Controller module. It
should be replaced while the chassis is powered up (hot-swapped).
NOTE: Ensure that the RAID Controller or LBB you are installing has the same
microcode version as the module being replaced. Otherwise, the replacement
module will not initialize. Refer to the Profile XP System Guide for information on
checking controller firmware versions.
NOTE: A PFR500 must have at least one RAID Controller installed while it is
powered up. Do not remove both RAID Controller while the PFR500 is powered up.
Removing the LBB or RAID Controller
NOTE: Removing or inserting the RAID Controller or LBB causes approximately
a 10 second loss of video (record/play). This happens regardless of whether you are
exchanging the primary controller or the secondary controller.
To remove the LBB or RAID Controller:
1. Identify the module to be replaced using NetCentral or rear panel LED indicators.
2. Remove the cables connected to the module. Note where the cables connect to the
module.
3. Loosen captive screws as shown in the figure below.
