n Step Action
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 termination on an external LAN connector (power entry
compartment at rear of frame).
2 Verify that the span line is disconnected at the Span I/O card. If the span 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 LAN (LAN A) at the LAN shelf
below the SCCP cage. If LAN A is not the active LAN, force a LAN switch to
LAN A by following the procedure in Table 6-2.
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 external LAN connectors are properly terminated (power entry
compartment at rear of frame).
8 Verify a T-adapter is not used on LMF computer side connector when connected
to the primary LAN at the LAN shelf.
9 Try connecting to the Ethernet Out port in the power entry compartment (rear of
frame). Use a TRB–to–BNC (triax–to–coax) adapter at the LAN connector for this
connection.
10 Re-boot the CDMA LMF and retry.
11 Re-seat the MGLI2 and retry.
12 Verify GLI2 IP addresses are configured properly by following the procedure in
Table 6-3.
Table 6-2: Force Ethernet LAN A to Active State as Primary LAN
n Step Action
1 If LAN A is not the active LAN, make certain all external LAN connectors are
terminated with 50Ω loads or cabled to another frame.
2 If it has not already been done, connect the LMF computer to the stand–alone or
starter frame, as applicable (Table 3-6).
3 If it has not already been done, start a GUI LMF session and log into the BTS on
the active LAN (Table 3-7).
