Linux PBX repair

- Responded to a complaint that phones were down. Arrived

onsite and pinged the in-house PBX at with no response. Investigated console and found power on but screen black. Upon reboot, encountered "kernel panic" error

preventing Linux startup. The controller bios showed the

mirrored drive status as "degraded". Efforts to boot the

remaining drive failed (due to universally panned capability

of this particular Dell "RAID" controller). - Booted the PBX box with a bootable Linux flash drive and successfully saved PBX files necessary for an emergency


- Installed new replacement drive then installed Linux Centos.

- Configured the network adapter, installed SSH. Established

access to the PBX via Windows computer running Putty.

- Performed restore operation then successfully tested phones

for proper operation.
