Understanding calibration purpose
IP-RN 8000 Installation & Commissioning Guide 171
Understanding calibration purpose
The purpose of the procedures in this chapter is to measure the power loss over the antenna jumper so that
you can adjust the transmission level for the sector appropriately to compensate.
Understanding requirements
The following are required to measure and calibrate the transmit power for each sector:
• The IP-RN 8000 must have been completely configured for normal operations with the commissioning
script.
• Backhaul links must be operative at the physical level and at the IP level providing connectivity to the
IP-RNC 8500 to which this IP-RN 8000 is homed.
• The IP-RNC 8500 to which this IP-RN 8000 is homed must be operating.
• You must know the management IP address of the IP-RNC 8500 to which the IP-RN 8000 is homed in
order to telnet to it.
Understanding the need for simultaneous CLI sessions
Calibrating transmit power requires two simultaneous CLI sessions, one to the local IP-RN 8000 and one to
the remote IP-RNC 8500. Simultaneous CLI sessions require a connection from the laptop to the BIO/SC
craft Ethernet port and that the appropriate IP configuration is completed. Once this connection is active,
you can open two CLI/telnet sessions, one to the local IP-RN 8000 and one to the remote IP-RNC 8500.
(Alternatively, you can use the CLI/serial connection to control the local IP-RN 8000 and use CLI/telnet to
control the remote IP-RNC 8500.)
Before proceeding, open these two CLI sessions. Opening the IP-RNC 8500 requires that you know and use
the IP-RNC 8500’s management IP address.
