Status LEDs
The AC44 Card has 4 status LEDs that dis-
play information about the communication
status. Table 1 below shows the meaning of
each status LED.
The status LEDs are only visible when the
IPLink is powered on. They are primarily
used to troubleshoot problems on the com-
munication line.
E2E can upgrade the software on a
communication card from a remote
location. When this is being done,
all 4 LEDs on the card are lit for
about 7 seconds. DO NOT TURN
OFF POWER to the IPLink while an
upgrade is ongoing since this will
cause permanent damage to the card.
DO NOT turn off power to the IPLink
when 4 LEDs are simultaneously lit on
the communication card (unless they
stay lit for more than 30 seconds).
