Status
Status/Summary Alarm indicator illuminates during the power-on
or reboot cycle for the following conditions:
•
Blinking Red — powered on and performing initial boot
code memory tests.
•
Blinking Yellow — boot code memory tests have
passed. Performing low level initialization. This includes
initialization of processor, requesting BOOTP or DHCP,
and downloading of OM application files.
•
Blinking Green — OM has loaded application code and is
performing final hardware initialization. This also includes
start up of all software tasks.
After the OM has completed booting, the Status/Summary Alarm
indicator illuminates for the following conditions:
•
Solid Green — power on and no faults.
•
Solid Yellow — indicates a minor or warning alarm has
occurred.
•
Solid Red — indicates a critical or major alarm has
occurred.

Indicates when data arrives from the cable network.
4
RF and IF Output indicators — each illuminates to indicate data
activity as follows:
•
Off — no link or link down (the auto-negotiation failed,
no communication to partner, or no link pulse observed).
•
Solid Green — link up (auto-negotiation link pulse
activity, partners agree on capabilities, but no data
traffic).
•
Solid Yellow — Mute.
•
Solid Red — faulty or failed.

10/100Base-T Ethernet indicators 1 and 2 — each illuminates to
indicate Ethernet link, data, and collision status as follows:
•
Off — no link or link down (the auto-negotiation failed,
no communication to partner, or no link pulse observed).
•
Solid Green — link up (auto-negotiation link pulse
activity, partners agree on capabilities, but no data
traffic).
•
Alternating Green-Yellow — collision detected (if in
half-duplex mode, 10/100Base-T only). Light LED for
100 msec after detection of collision. During high
collisions appears as alternating green-yellow.
