actual hardware versions are identical. If there is a difference in the configured
and actual versions, an alarm is raised.
The hw_version parameter indicates the current supply capability of the PIU: 58A
(high-power PIU) or 35A.
To configure the PIU hardware version, run the following command:
npu(config)# PIU <slot id (1-2)> hw_version <version (5-6)>
3.4.16.2 Configuring the GPS
The GPS is used to synchronize the air link frames of Intra-site and Inter-site
located sectors to ensure that in all sectors the air frame will start at the same
time, and that all sectors will switch from transmit (downlink) to receive (uplink)
at the same time. This synchronization is necessary to prevent Intra-site and
Inter-site sectors interference. In addition, the GPS synchronizes frame numbers
that are transmitted by the AU.
