DSR® Switch Installer/User Guide
Verifying the Connections
DSR switch
The front panel of the DSR switch features LEDS indicating the Ethernet connection for both
LAN1 and LAN2 (if applicable), as well as LEDS that indicate the target device status for each
port. Both the front and back panels feature a power LED that indicates the power status of the
DSR switch.
Power LEDs
•
The green LEDs illuminate when the DSR switch is turned on and is operating normally.
•
The green LEDs will blink slowly for several seconds when the DSR switch is first turned
on.
•
The green LEDs will blink slowly and continuously if the DSR switch has experienced a
Flash upgrade failure.
•
For DSR switch models that are equipped with dual power supplies, the green LEDs will
blink quickly if one of the power supplies fails or is not connected, and will continue to
blink as long as the failure persists.
•
When the DSR switch is turned off, the green LEDs will not be illuminated.
Ethernet connection LEDS
•
The green LED, labeled Link, illuminates when a valid connection to the network is
established at the maximum supported rate and blinks when there is activity on the port.
•
The amber LED illuminates when you are communicating at a slower rate when using an
Ethernet connection.
•
If neither LED is illuminated, connection speed is at a rate of 10 Mbps.
Target device status LEDS
•
A green LED illuminates when the attached target device has power.
•
An amber LED illuminates when that port is selected.
•
The LEDs blink during a firmware upgrade.
IQ and serial IQ modules
Typically, IQ modules feature two green LEDs: a POWER LED and a STATUS LED.
•
The POWER LED indicates that the attached module is powered.
•
The STATUS LED indicates that a valid selection has been made to a DSR switch.
