Testing MCUF
redundancy
The following procedure tests MCUF redundancy by forcing the master and
redundant MCUFs to swap roles. The commands refer to the base transceiver
processors (BTPs) within each MCUF.
1. Connect a PC to the TTY connection on the master MCUF.
2. At the CUST MMI prompt, type:
state <site #> btp * *
Where <site #> is the site number.
The status of both BTPs will be displayed as follows:
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 E–U NO REASON
Where B–U is busy unlocked (master) and E-U is enabled unlocked
(redundant).
3. At the CUST MMI prompt type:
swap_devices <site #> btp 0 0 0 btp 1 0 0
Where <site #> is the site number, btp 0 0 0 is the master MCUF and btp
1 0 0 is the redundant MCUF.
This command will swap MCUF roles by forcing:
 the redundant MCUF into a busy state , and making it master.
 the master MCUF into an enabled state, and making it redundant.
4. At the CUST MMI prompt, confirm the swap by typing:
state <site #> btp * *
Where <site #> is the site number.
The status of both BTPs will now show changed roles:
BTP 0 0 0 E–U NO REASON
BTP 1 0 0 B–U NO REASON
5. Make test calls on the site to verify the new master MCUF.
6. At the CUST MMI prompt type, swap the MCUFs back to their original
states by typing:
swap_devices <site #> btp 1 0 0 btp 0 0 0
Where <site #> is the site number, btp 1 0 0 is the master MCUF and btp
0 0 0 is the redundant MCUF.
7. At the CUST MMI prompt, confirm the swap by typing:
state <site #> btp * *
Where <site #> is the site number.
Both BTPs have now reverted to their original roles:
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 E–U NO REASON
8. Make test calls on the site to verify the new master MCUF.
