Off The MVI56-104S is working normally. APP Amber
On The MVI56-104S module program has recognized a
communication error on one of its ports.

operation on the backplane. BP ACT Amber

operation on the backplane. Under normal operation, the LED
should blink rapidly on and off.

plugged into the rack.

OK Red/
Green
Red The program has detected an error or is being configured. If
the LED remains red for over 10 seconds, the program has
probably halted. Remove the card from the rack and re-insert
the card to restart the module’s program.
Off The battery voltage is OK and functioning. BAT Red
On The battery voltage is low or battery is not present. Allow
battery to charge by keeping module plugged into rack for 24
hours. If BAT LED still does not go off, contact ProSoft
Technology, as this is not a user serviceable item.
If the APP, BP ACT and OK LEDs blink at a rate of every one-second, this
indicates a serious problem with the module. Call ProSoft Technology support to
arrange for repairs.
In addition to these LEDs, the module contains two LEDs under the module’s
door. The LED on the left (green) displays the link status. If the module is
connected properly to a Hub, this LED should be illuminated. The LED on the
right (amber) is the data indication LED. Whenever the module is sending or
receiving data on the Ethernet interface, this LED will be illuminated.
