Table C-5 Warnings/Status Messages for Main Hubs
Message
Number/
Default Description Reason/Action
[M01]/S Fan 1 failure. Check the fan for rotation, air flow blockage, and dust.
Replace the Hub on high temperature warning.
[M02]/S Fan 2 failure. Check the fan for rotation, air flow blockage, and dust.
Replace the Hub on high temperature warning.
[M03]/S 54 VDC Pwr Supply Fan failure. Check the fan for rotation, air flow blockage, and dust.
Replace the Hub on high temperature warning.
[M04]/W 5 VDC Monitor. DC power out of range, replace the Hub.
[M05]/W 9 VDC Monitor. DC power out of range, replace the Hub.
[M06]/W 54 VDC Monitor. DC power out of range, replace the Hub.
[M07]/W 3 VDC Monitor. DC power out of range, replace the Hub.
[M08]/W 12 VDC Monitor. DC power out of range, replace the Hub.
[M09]/W Temperature High. Reduce ambient temperature, check for air flow blockage,
fan rotation.
[M10]/W -5 VDC Monitor. DC power is out of range, replace the Hub.
[M11]/W High laser current. Output laser failure possible, replace the Hub when possi-
ble.
[M12]/W DL path loss is too high Replace the Hub.
[M13]/S Low input optical (Port 1). Check the uplink fiber.
[M14]/S Low input optical (Port 2). Check the uplink fiber.
[M15]/S Low input optical (Port 3). Check the uplink fiber.
[M16]/S Low input optical (Port 4). Check the uplink fiber.
[M17]/S Hardware failure (Test Tone PLL
Band 1).
Unable to perform DL system test.
[M18]/S Hardware failure (Test Tone Too
High Band 1).
Unable to perform DL system test.
[M19]/S Hardware failure (Test Tone Too
Low Band 1).
Unable to perform DL system test.
[M20]/W Overdrive limiter active (Band 1). Reduce input signal power to avoid potential component
damage.
[M21]/W CEMark limiter at maximum
(Band 1).
Reduce input signal power to avoid drop in system gain.

possible.
[M27]/S Hardware failure (Test Tone Too
Low Band 2).
Unable to perform DL system test. Replace the hub when
possible.
[M28]/W Overdrive limiter active (Band 2). Reduce input signal power to avoid potential component
damage.
[M29]/W CEMark limiter at maximum
(Band 2).
Reduce input signal power to avoid drop in system gain.
