Nine-pin RS-232 Test Port (behind front bezel) — an interface
used to access internal diagnostics from the operating system
command line shell. It also provides an alternate method to
configure the OM.
• Top row connector pins are: 5, 4, 3, 2, 1
• Bottom row connector pins are: 9, 8, 7, 6
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
o c c u r r e d .
• Solid Red — indicates a critical or major alarm has
o c c u r r e d .
Indicates when data arrives from the cable network.

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
t r a f fi c ) .
• S o l i d Ye l l o w — M u t e .
• 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
t r a f fi c ) .
• 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.
