Utilization Alarm LEDs
Four LEDs indicate that utilization levels have exceeded the threshold. Each LED
is the alarm for one port. For Network Ports, utilization is monitored on incoming
traffic; for Monitor Ports, the outgoing traffic is monitored. When a Utilization
Alarm LED is illuminated, it indicates that the threshold level was exceeded for that
port since the last reset. The LEDs remain illuminated until they are reset using the
reset button or remote interfaces.
Link LEDs
Four LEDs indicate link status. If a good link is established on a port, the LED
corresponding to that port illuminates. The Link LED blinks when traffic is passing
through the port; the intensity of the blinking increases with the utilization; it
becomes noticeable for utilizations of about 30 percent or greater.
Mode LEDs
If the device is in Tap mode, the TAP LED illuminates. If the device is in Aggrega-
tion mode, the AGG LED illuminates. (If both mode LEDs are illuminated or both
are off, check that the Mode bits are set to the same value for both Monitor Ports.)
Power LEDs
If the iTap Port Aggregator is deployed with both power supplies, both power
LEDs illuminate when connected to power. If a power LED is off, the correspond-
ing power supply is disconnected or not functioning.
Reset Button
Press the Reset button to reset the traffic peaks and times on the display, and the
Utilization Alarm LEDs. To prevent accidental resets, the Reset button is recessed
into the front panel. To push the Reset button, use a thin, rigid tool such as a paperclip.
The traffic peak and time can also be reset using the CLI or remote interfaces.
