APPENDIX A: UPGRADING AN LPA

CAUTION! Completing this upgrade causes a Loss of Service. Complete this procedure during

normal maintenance time.

NOTE: Any LPA firmware version prior to V1.13 identifies itself as a URH PCS LPA via the I2C.

Only LPAs upgraded to V1.13 will correctly identify themselves via I2C. You can upgrade

any LPA with this utility.

NOTE: The UMTS LPA is used as an example in this document.

Do the following to upgrade an LPA.

1 Ensure that your laptop Network-Interface Connection (NIC) is configured for

DHCP.

2 Access the Hardware Inventory report for the Host and Remote Unit(s):

a In the System Menu bar, click System Information > Get Information,.

b In the Reports panel Type list, select Hardware Inventory.

c Determine the IP address for the Host and Remote Unit(s).

d Determine the number of the LPA that you want to upgrade; see “RF Module

Capabilities and GUI Representation” on page 21

3 Login to the Host using telnet or ssh.

4 From the Host, login to the Remote Unit using the following command, where

N is the Remote Unit ID (1 - 8):

sshremote N

9 To see the inventory of the unit to be upgraded, enter the module slot number

that you obtained in

Step 2.

NOTE: If the unit has V1.12 or earlier firmware on it, it will always self identify as a URH 1.9GHz

PCS LPA regardless of its actual LPA type. This has been corrected in version 1.13. In this

example, although the unit is reported as URH1.9, it is actually a UMTS module.

10 To upgrade the LPA, type the number that corresponds to the LPA to be

upgraded.

11 Select the firmware to use during the upgrade.
