Troubleshooting Non-responsive CMC

VRTX Chassis unresponsiveness of CMC using any of the interfaces (the Web interface, Telnet, SSH,

remote RACADM, or serial), you can diagnose by observing the LEDs on CMC, obtaining recovery

information using the DB–9 serial port, or recovering the CMC firmware image. It is not possible to

Observing LEDs to Isolate the Problem

When the VRTX Chassis enclosure is opened, the Mainboard has two CMCs installed on the respective

slots and there are two LEDs on the side of the card. Top green LED indicates power. If it is not

turned on, verify that you have an AC power connected to at least one PSU.

Also make sure the CMC card is installed properly on the slots. Before the CMC is pulled out, make

sure the Chassis is passive, and then remove CMC, reinstall CMC making sure the board is inserted all

the way and that the latch closes correctly.

Bottom LED — the bottom LED is multi-colored. When CMC is active and running, and there are no

problems, the bottom LED is blue. If it is amber, a fault was detected. The fault may be caused by

any of the following:

 A CMC Core failure, the CMC board must be replaced.

 A CMC Self-test failure, the CMC board must be replaced.

 Corrupted CMC Firmware and Recovery image. An image corruption can be rectified by

uploading the CMC firmware image to recover the CMC (see Recovering Firmware Image).

A normal CMC start or reset takes about a minute to fully boot into its operating system and be

available for log in. The blue LED is illuminated on the active CMC. In a redundant, two-CMC

configuration, only the top green LED is illuminated on the standby CMC.

Recovering Firmware Image

CMC enters recover mode when a normal CMC operating boot is not possible. To utilize recovery

mode, connect a null modem cable to the VRTX Chassis serial port. In recover mode, a small subset

of commands are available that allow you to reprogram the flash devices by uploading the firmware
