LED indicators
The
CX-6p-PoE has twelve LED indicators on the front of the unit, associated
with the Ethernet switch and PoE function, and four on the back of the unit,
associated with the environmental monitoring and communications functions.
Front panel indicators – Ethernet connection status
The front panel of the CX-6p-PoE has two LEDs located above each of the first
four RJ45 Ethernet ports. The LED on to the left of each port is a combined
link/activity LED which will illuminate a solid green when an Ethernet link
connection has been made, and will flash rapidly to indicate link activity. The
LED on the right side of each port will illuminate green if power is being provided
to the PoE powered device connected to that port.
Adjacent to each of ports 5 and 6 (the two SFP ports to the right of the first four
ports) are two more LEDs. The upper LED indicates if an optical link is detected
on the port. This LED will illuminate LED if no optical link is detected, and green
if an optical link is detected. The lower LED is a combined link/activity indicator.
It will illuminate green when an Ethernet connection is detected on the port, and
flash rapidly to indicate link activity.
Rear panel indicators – Environmental monitoring functions
There are four LEDs on the rear of the device, arranged in two groups of two, on
the right side of the device as seen from the rear.
Probe status LEDs
There are two LEDs located in between the RS232 serial port and the
environmental probe connectors. These two LEDs indicate the status of the two
environmental probes. These LEDs will each be off if the associated probe is not
installed, green if it is installed and all monitored parameters are within normal
ranges, and red if any of the monitored environmental parameters are outside of
warning or alarm ranges.
Status/Alarm LED
On the right side of the rear panel of the unit are two LEDs. The upper of these
two LEDs indicates the unit’s power and overall alarm status. This LED will
normally light green when the unit is powered. It will illuminate red if the ambient
temperature is above 70C or below 0C, or if an internal hardware problem is
detected in the CX-6p-PoE.
