1 If MGLI2 LED is solid RED, it implies a hardware failure. Reset MGLI2 by
re-seating it. If this persists, install RGLI2 card in MGLI2 slot and retry. A Red
LED may also indicate no Ethernet termination at top of frame.
2 Verify that T1 is disconnected at the Channel Signaling Unit (CSU). If T1 is still
connected, verify the CBSC has disabled the BTS.
3 Try ‘ping’ing the MGLI2.
4 Verify the LMF is connected to the Primary LMF port (LAN A) in front of the
BTS.
5 Verify the LMF was configured properly.
6 If a Xircom parallel BNC LAN interface is being used, verify the BTS-LMF cable
is RG-58 (flexible black cable of less than 2.5 feet length).
7 Verify the Ethernet ports are terminated properly.
8 Verify a T-adapter is not used on LMF side port if connected to the BTS front
LMF primary port.
9 Try connecting to the Ethernet Out port in the power entry compartment (back of
frame). Use Triax to BNC adapter at the LMF port for this connection.
10 Re-boot the CDMA LMF and retry.
11 Re-seat the MGLI2 and retry.
12 Verify IP addresses are configured properly.
