iBypass Switches with Heartbeat
8
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 Using the Command Line Interface in chapter 2).
Threshold Alarm LEDs
Four LEDs indicate that utilization levels have exceeded the threshold. There is one
LED per port for incoming traffic on the front panel. When a Threshold 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.
(Threshold alarm LEDs are not provided on the 10/100/1000 iBypass Switch.)
Link LEDs
Four LEDs indicate link status. If a good link is established, the LED illuminates a
steady green. If there is no current activity on this link, the LED flashes.
Power LEDs
If the iBypass Switch is deployed with both power supplies, both power LEDs
will illuminate when connected to power. If a power LED is off, the corresponding
power supply is not functioning or connected.
Reset Button
Press the Reset button to reset the traffic peak and time on the display and the
Threshold 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.
