8.4.1 System LEDs
The front panel of the terminal includes a number of LEDs to monitor operation of the
system and assist troubleshooting. Refer to section 3: Physical Description on page 26.

8.4.2 Console Port
The front panel includes the Console port. Use the CLI commands to interrogate the
base station status and program most system settings.

8.4.3 System Reset Switch
Throughout this section, reference is made to the reset switch, which is a micro-switch
recessed in the front panel in the system block. Use a small narrow object, such as a
paper clip, to access the switch.

Depressing the reset switch for less than five seconds activates a short-reset (equivalent
to power-cycle). Statistical values are reset.

Detecting Channel Interference at Startup
Following a power-cycle or reboot, the base station monitors the RF Channel to detect
interference on the uplink channel. The transceiver is set to receive mode and the PHY
is programmed to receive a long preamble from a WiMAX base station. If no preamble is
detected during the one-second interval, the channel is considered free of interference
from other WiMAX equipment.

is programmed to receive a long preamble from a WiMAX base station. If no preamble is
detected during the one-second interval, the channel is considered free of interference
from other WiMAX equipment.
If a long preamble is received, the base station continues to monitors the channel for an
additional three seconds. If an 802.16d DL-Map is received, the following message will
be entered into the event log:
additional three seconds. If an 802.16d DL-Map is received, the following message will
be entered into the event log:
WARNING: RF Channel Conflict with [BS Id]
This message in the event log indicates that another base station has been detected
using the following RF-PHY characteristics:
using the following RF-PHY characteristics:
- Same DL channel frequency as the UL channel frequency of this SC
- Same Cyclic Prefix
- Same channel size (i.e., 7 MHz)
If a long preamble was received, but no DL-Map was detected, the following message
will be entered into the event log:

WARNING: Unknown Interference was detected on the UL channel
This second message does not necessarily indicate interference from another base
station, and may be the result of cross-interference from subscribe stations.
