This chapter provides troubleshooting data necessary for fault isolation and preventive maintenance guidelines.

The procedures presented in this chapter assume that a Level I fault has led the user to suspect a fault with the 
RF-7800W HCLOS Radio. The user begins the troubleshooting process with the Factory Reset procedure.

The maintainer will use the status code/system log troubleshooting procedures if there is a fault as a result of a status 
code or system log. The maintainer will use the non-BIT troubleshooting procedure if there is a non-Built-in Test 
(BIT) fault. The radio system is returned to operational readiness once the problem is found and corrected.

Troubleshooting starts with the factory reset procedure described below. 

Factory defaults can be restored using either the Command 
Line interface (CLI) command of save defaultconfig [Enter] 
or Factory Defaults utility in the Navigation menu (left side 
pane) of the GUI.

See 

. It may be necessary to reset to the factory IP address (e.g. due to lost admin user name and 

password). This can be accomplished by having local access to the Power over Ethernet (PoE) Injector, the ability 
to power-cycle the RF-7800W HCLOS Radio, a PC with a Telnet client, and an Ethernet cable. Perform the 
following procedure to reset the factory default IP address:

a.

Connect a PC to the input connector of a PoE Injector using an Ethernet cable.

b.

Connect the RF-7800W HCLOS Radio to the output connector of the PoE supply using an Ethernet 

cable and leave the radio powered on for a few minutes. 

c.

Open a command prompt window on the PC and type telnet 192.168.26.2 without pressing [Enter]. 

d.

Open a second command prompt window, type ping 192.168.26.2 -t, and press [Enter].

e.

Remove power from the radio for approximately six to eight seconds by disconnecting the Ethernet 

cable from the Output connector of the PoE Injector and then reconnecting.

f.

Observe that pings return from 192.168.26.2 (approximately 2 minutes 40 seconds).

g.

Press [Enter] in the Telnet window on the PC. 

h.

Observe the Login prompt, and if you do not see the Login prompt, repeat the command telnet 

192.168.26.2 and press [Enter] until you see the prompt.
