iTap Dual Port Aggregator
1
The percentage utilization data on the display is refreshed every second.
Network peaks are given as a percent of utilization and reflect the highest peak
recorded since the last reset. The day and time information reflects the highest
peak event since reset. You can set the iTap's 24-hour clock through the CLI or
remote interfaces.
For example:
If you have set the thresholds for 30% utilization on Friday and during the week-
end several peaks over this level occur, the iTap provides information only on the
highest peak event.
If data is not displaying as expected, check the Network Port connectors for link
status and activity. Also check the status of the Display command using the CLI
(see page 11).
Utilization Alarm LEDs
There are two LEDs indicating when the utilization levels have exceeded the
threshold. There is one LED for incoming traffic on each Network Port. When a
Utilization Alarm LED is red, it indicates that the threshold level was exceeded for
that port since the last reset. The LEDs remain illuminated until reset via the reset
button or remote interfaces.
Link LEDs
The RJ45 connectors have two LEDs for link status. If a good link is established,
the right LED illuminates a steady green. If there is current activity on this link,
the left LED flashes.
Power LEDs
If the iTap is deployed with both power supplies, both power LEDs illuminate
when the iTap is connected to power. If an LED is off, the corresponding power
supply is not functioning.
Reset Button
Use the Reset button
to quickly reset the traffic peak and time on the display and
the Utilization Alarm LEDs. To prevent accidental resets, the Reset button is
recessed from the front panel. To push the Reset button, use a thin, rigid tool such
as an unbent paperclip.
