Verifying the Connections
Front and rear panel Ethernet connection LEDs
On 16-port and 32-port models of the MergePoint Unity switch, the front and rear panels feature two LEDs
indicating the Ethernet LAN1 connection status and two LEDs indicating the Ethernet LAN2 connection status.
On the 4-port and 8-port switches, all LEDs are on the rear panel.
• The green LEDs illuminate when a valid connection to the network is established and blink when there is
activity on the port.
• The bi-color LEDs may illuminate either green or amber.
• They illuminate green when the communication speed is 1000M.
• They illuminate amber when the communication speed is 100M.
• They are not illuminated when the communication speed is 10M.
Front panel status LEDs
The front panel of MergePoint Unity switches (16-port and 32-port models only) have a bi-color general status
LED that may illuminate green or amber.
• The LED illuminates green when the MergePoint Unity switch is turned on and operating normally.
• The LED blinks green when the MergePoint Unity switch is booting.
• The LED illuminates amber if a fault condition occurs, such as power supply failure (for MergePoint Unity
switches equipped with dual power supplies), elevated ambient temperature or fan failure. The LED will
continue to illuminate amber as long as the failure persists.
• The LED blinks between green and amber when the MergePoint Unity switch is Flash downloading.
Rear panel power status LEDs
The rear panel of 16-port and 32-port MergePoint Unity switches feature one power status LED for single power
MergePoint Unity switches and two power status LEDs for dual power MergePoint Unity switches. On the 4-
port and 8-port switches, all LED status indicators are on the rear panel. The LED(s) illuminate green when the
MergePoint Unity switch is turned on and operating normally.
• The LED is off if the power supply does not have power or has failed.
