Enable CSMs
Follow the steps outlined in Table 3-16 to enable the CSMs installed in
the SCCP shelves.
Table 3-16: Enable CSMs
n Step Action
1
NOTE
If equipped with two CSMs, enable card in slot CSM 2 first.
Click on the target CSM.
2 Click on Device in the BTS menu bar, and select Enable in the pull–down menu list.
– A status report is displayed showing the results of the enable operation.
– Click OK to close the status report window.
NOTE
– The board in slot CSM 1 interfaces with the GPS receiver. The enable sequence for this board can
take up to one hour (see below).
– FAIL may be shown in the status report table for a slot CSM 1 enable action. If
Waiting For Phase
Lock is shown in the Description field, do not cancel the enable process. The CSM will change to
the Enabled state after phase lock is achieved.
* IMPORTANT
– The GPS satellite system satellites are not in a geosynchronous orbit and are maintained and
operated by the United States Department of Defense (DOD). The DOD periodically alters
satellite orbits; therefore, satellite trajectories are subject to change. A GPS receiver that is INS
contains an “almanac” that is updated periodically to take these changes into account.
– If a GPS receiver has not been updated for a number of weeks, it may take up to an hour for the
GPS receiver “almanac” to be updated.
– Once updated, the GPS receiver must track at least four satellites and obtain (hold) a 3–D position
fix for a minimum of 45 seconds before the CSM will come in service. (In some cases, the GPS
receiver needs to track only one satellite, depending on accuracy mode set during the data load).
NOTE
– If two CSMs are installed and the board in slot CSM 1 has enabled, the LMF CSM cage view
should show slot CSM 1 as bright green (INS–ACT) and slot CSM 2 as dark green (INS–SBY)
– After CSMs have been successfully enabled, be sure the PWR/ALM LEDs are steady green
(alternating green/red indicates the card is in an alarm state).
3 If more than an hour has passed without the board in slot CSM 1 enabling, refer to the CSM System
Time – GPS & LFR/HSO Verification section of this chapter (see Table 3-18, Figure 3-10, and
Table 3-19) to determine the cause.
