Nokia Solutions and Networks T5EJ1 Manual Do Utilizador

MAY 2004

 11-1

The information in this chapter addresses some of the scenarios likely to
be encountered by Customer Field Engineering (CFE) team members
while performing BTS optimization and acceptance testing. This
troubleshooting guide was created as an interim reference document for
use in the field. It provides “what to do if” basic troubleshooting
suggestions when the BTS equipment does not perform according to the
procedures documented in the manual.

Comments are consolidated from inputs provided by CFEs and
information gained from experience in Motorola labs and classrooms.

Table 11-1: Login Failure Troubleshooting Procedures

1

If the GLI LED is solid RED, it implies a hardware failure. Reset GLI by re-seating it. If this persists,
install GLI card in GLI 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 to ‘ping’ the GLI.

4

Verify the LMF is connected to the primary LAN (LAN A) at the LAN shelf below the CCP2 cage. If
LAN A is not the active LAN, force a LAN switch to LAN A by following the procedure in
Table 11-2.

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 less than 2.5 feet in 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 LMF and retry.

11

Re-seat the GLI and retry

12

Verify GLI IP addresses are configured properly by following the procedure in Table 11-3.
