Step 2. Verify that the Ethernet Link LED, which is the green LED on the
left, is on.
Step 3. If the LED is on, go to step 4.
If the LED is not on, proceed to “Before Removing or Replacing
the Unit” on page 82.
Continue through “Replacing the SNC 5100” on page 84.
Exit this MAP.
Step 4. Determine the speed of the network, by following the procedure in
“Perform Health Check” on page 46.
If the Health Check generates a Trap Event Code of 115, then the
SNC 5100’s yellow Speed LED should be on.
Verify that the yellow Speed LED, which is the yellow LED on the
right, correctly reflects the speed of the network.
Step 5. If the yellow Speed LED correctly reflects the speed of the
network, go to Step 7.
If the yellow Speed LED does not correctly reflect the speed of the
network, go to Step 6.
Step 6. Inform the System Administrator that there may be a problem with
the Ethernet cable quality, the intermediate link speeds or
interconnect speeds.
If the System Administrator can find no problems with the Ethernet
cable quality, the intermediate link speeds, or interconnect speeds,
but the SNC 5100 yellow Speed LED does correctly reflect the
network speed, go to “Before Removing or Replacing the Unit” on
page 82.
Continue through “Replacing the SNC 5100” on page 84.
Exit this MAP.
Step 7. Remove the Ethernet cable from the SNC 5100 Ethernet Port and
attach the Ethernet loop back plug.
Step 8. Verify that the Ethernet LEDs are functioning correctly.
If they are, proceed to Step 9.
