CSM Frequency Verification
The objective of this procedure is the initial verification of the Clock
Synchronization Module (CSM) cards before performing the RF path
verification tests.
Test Equipment Setup
(GPS & LFR/HSO Verification)
Follow the steps outlined in Table 3-18 to set up test equipment.
Table 3-18: Test Equipment Setup (GPS & LFR/HSO Verification)
Step Action
1 Perform one of the following as required by installed equipment:
1a
– For local GPS (RF–GPS): Verify a CSM card with a GPS receiver is installed in the primary
CSM slot, CSM 1, and that the card is INS_ACT (bright green).
NOTE
Verify by checking the card ejectors for kit number SGLN1145 on the card in slot CSM 1.
1b
– For Remote GPS (RGPS): Verify a CSM–II card is installed in primary slot CSM 1 and that the
card is INS_ACT (bright green).
NOTE
Verify by checking the card ejectors for kit number SGLN4132ED or subsequent.
2 Remove the card from slot CSM 2 (if installed) and connect a serial cable from the LMF COM 1 port
(via null modem card) to the MMI port on the card in slot CSM 1 (see Figure 3-10).
3 Reinstall the card removed from slot CSM 2.
4 Start an MMI communication session with the card in slot CSM 1 by using the Windows desktop
shortcut icon (see Table 3-10) .
5 When the terminal screen appears press the Enter key until the CSM> prompt appears.
CAUTION
In the power entry compartment, connect the GPS antenna to the
RF GPS connector ONLY. Damage to the GPS antenna and/or
receiver can result if the GPS antenna is inadvertently connected
to any other RF connector.
