Task 6: Configuring protection Chapter 6: Configuration and alignment
6-62
phn-2513_004v000 (Oct 2012)
To implement protection on an unprotected link, follow this process:
1
To pre-configure the two new CMUs during staging before site installation (if this
is required), perform the following tasks from Chapter 6: Configuration and
alignment for each CMU:
from Task 1: Connecting to the unit on page 6-3,
to Task 11: Configuring remote access on page 6-96.
Perform these tasks after installation, if preferred.
2
In the field, upgrade the operational CMUs to the latest software version by
performing Task 4: Upgrading software version on page 6-25.
3
In the field, configure the operational CMUs for protected operation by
performing Task 6: Configuring protection on page 6-53.
If this is done in advance of installation of the new CMUs, the PTP 800 will
still be operational and the wireless link can operate with single units, but
alarms will be issued due to the absence of protecting units.
The Protected link page is now available with local and remote ends shown as
unprotected, see Viewing the status of a 1+1 Hot Standby link on page 7-33.
4
Install and test the new hardware by following the relevant procedures in this
chapter.
5
Align the antennas and complete the configuration. Perform the following tasks
from Chapter 6: Configuration and alignment:
from Task 12: Aligning antennas on page 6-98,
to Task 15: Connecting link to the network on page 6-114.
6
Initiate a protection switch so that the link is running Primary to Primary. If
primary recovery is set, the units will switch automatically after the timer has
expired.
