Procedure 3-1 Troubleshoot VC-2402 Power Up Problems
Problem indication:
• the SYS LED on the front panel is not lit even though the DSLAM is powered up
• alarm that indicates a system power up problem
• subscribers connected to the DSLAM do not have DSL service; POTS service is
ok
1 Check that the power switch on the front panel is set to the ON position.
2 Check that the power feeds are connected to the DSLAM, and that power is
present on the two power feeds with correct polarity.
3 Replace the VC-2402.
4 Contact your provider.
Procedure 3-2 Troubleshoot Fiber Optics Problems
Problem indication:
• the GBE1/GBE2 LED on the system front panel is not lit (maybe the signal
power detected by the fiber optical receiver being below the minimum power
threshold) but the SFP interface has been activated
• alarm that indicates loss of signal
• subscribers connected to the DSLAM do not have DSL service; POTS service is
ok
1 Check the connection of the fiber optics link. Check that the connections are
secure and that the transmit and receive connections are not reversed.
2 Disconnect the fiber optics link from the dual fiber optics connector and do a
physical loopback at the VC-2402.
a If the GBE1/GBE2 LED turns green, the problem is with the fiber optics link.
b If the GBE1/GBE2 LED does not turn green, the problem is with the DSLAM.
Follow Procedure 3-1 to troubleshoot the DSLAM.
3 If the problem is with the fiber optics cabling, clean or replace as appropriate.
4 Contact your provider.
