Cannot Log into Cell-Site
Follow the procedure in Table 6-1 to troubleshoot a login failure.
Table 6-1: Login Failure Troubleshooting Procedures
n Step Action
1 If the MGLI LED is solid RED, it implies a hardware failure. Reset the MGLI by re-seating it. If
this persists, install a known good MGLI card in the MGLI slot and retry. A Red LED may also
indicate no Ethernet termination at top of frame.
2 Verify that T1 is disconnected (see Table 3-4 on page 3-16).
If T1 is still connected, verify the CBSC has disabled the BTS.
3 Try pinging the MGLI (see Table 3-11 on page 3-34).
4 Verify the LMF is connected to the Primary LMF port (LAN A) in the front of the BTS (see
Table 3-5 on page 3-17).
5 Verify the LMF was configured properly (see Preparing the LMF section starting on page 3–6).
6 Verify the BTS-LMF cable is RG-58 [flexible black cable of less than 76 cm (2.5 feet) length].
7 Verify the Ethernet ports are terminated properly (see Figure 3-9 on page 3-33).
8 Verify a T-adapter is not used on the LMF side port if connected to the BTS front LMF primary
port.
9 Try connecting to the I/O panel (top of frame). Use BNC T-adapters at the LMF port for this
connection.
10 Re-boot the LMF and retry.
11 Re-seat the MGLI and retry.
12 Verify IP addresses are configured properly.
Cannot Communicate to Power Meter
Follow the procedure in Table 6-2 to troubleshoot a power meter
communication failure.
Table 6-2: Troubleshooting a Power Meter Communication Failure
n Step Action
1 Verify the Power Meter is connected to the LMF with a GPIB adapter.
2 Verify the cable setup as specified in Chapter 3.
3 Verify the GPIB address of the power meter is set to the same value displayed in the applicable
GPIB address box of the LMF Options window Test Equipment tab. Refer to Table 3-25 or
Table 3-26 and the GPIB Addresses section of Appendix F for details.
4 Verify the GPIB adapter DIP switch settings are correct. Refer to the CDMA 2000 Test Equipment
Preparation section of Appendix F for details.
