Replacing the PSM (only for PSE/W)
Whilst in the case of 1+0 configurations it is recommended to replace in any case the complete
IDU, in case of 1+1 configurations using PSE/W (in order to guarantee as far as possible service
continuity) it is recommended to replace only the PSM module of the failed PSE/W if it can be
recognized that there is some power failure.
Note:
during replacement of PSM, power is provided to both 1+1 systems by the other PSE/W.
To replace PSM the following procedure has to be followed.
1)
Take from the stock a spare unit with the same P/N of the unit to replace
2)
Wear the antistatic armlet and connect its termination to a grounded structure
3)
Turn off (position O) the power switch on the front of the PSM to be replaced
4)
Disconnect the power cable from the front panel
5)
Extract the PSM module from the PSE/W unscrewing the two screws on the front
6)
Insert the new PSM in the PSE/W and block the screws
7)
Reconnect the power cable on the front panel
8)
Turn ON (position I) the power switch on the front panel and check that the LED is ON
9)
Verify that the system continues regularly its operation.
