Troubleshooting
SYMPTOM(S)
COURSE OF ACTION
• NO POWER
• LOGO LED INDICATOR
FAILS TO ILLUMINATE
• “DEAD” SWITCH
Check the following:
1. Ensure the 4-pin male quick-lock power supply connector is plugged and locked into place
in the
POWER
port.
2. Check that the power cord is properly connected.
3. Verify that the external power source outlet has power available. Plug another device in the
outlet to determine whether power is active in that socket.
• NO SWITCH CONTROL
• NO SWITCH RESPONSE
1. Verify whether the problematic switch is physically connected to the console computer platform
from which control is being attempted. Also, verify that you have the correct console IP address
for the platform physically connected to the switch.
2. Confirm that the correct control cable is in use. A DRL460-6-6 cable (or DRL448-6 if daisy-
chained) must be used, because the control port is a modified RS232 which is compatible only
with these Fluke Networks-supplied cables. If the proper cable is used and still no response is
detected, then substitute with another DRL460-6-6/DRL448-6 cable — ideally one known to
operate correctly.
