To avoid the possibility of damaging an IBR by overdriving the front end of the receiver, prior
to connecting a power source, position the radios so that they are tilted away from each
other, facing downward, and separated by at least one meter.
Check the RSSI using the following CLI command in the Global Config mode:
IBR58 (config) # interface radio 0 status
RSSI should be -20dB or less. If RSSI is greater than -20 dB (e.g., -17dB, -15dB, etc.) then
further separate the radios to avoid receiver saturation.
4.2 Applying Power
CAUTION - IBR does not have a power on/off switch, either in hardware or software. When
power is applied to the unit, IBR will be in a “power on” condition and the lower LED beside
the Port 0 connector will be green unless the LED has been disabled by the operator.
Apply power to each IBR using a PoE+ source connected to Gigabit Ethernet interface 0.
4.3 Logging Onto IBR Using Factory-Set User Name & Password
When CLI is launched and the “user name” dialog box appears, the user can enter either fbn
or admin for access (unless the user name has been changed by an operator). The factory-
set password is fastback. When a user with Privileged access changes the user name,
changing either admin or fbn will cause both to be changed to the new user name.
4.4 Entering CLI User Mode
When a user logs onto IBR with a valid user name and password , CLI automatically will be in
the User Mode, which offers a limited set of commands. The CLI command prompt in User
Mode is the symbol > followed by a space. When the command prompt is displayed, it will
be preceded by the host name if one has been assigned. Throughout this manual and the CLI
Guide, the host name IBR58 will be used. The User Mode prompt is shown below:
IBR58 >
The host name can be changed or omitted by a Privileged user. The commands shown below
are the only commands available in User mode.
User Commands
Mode/Command Remarks
IBR> User Mode
enable Enter Privileged Mode
ping Determine (a) if a remote host is active & (b) transit time
traceroute Determine route & transit time to a remote host

4.5 Entering CLI Privileged Mode
Enter Privileged (“Priv”) mode by entering the enable command:
IBR58 > enable
The default password for entering Priv mode is fastback.
All CLI commands are available in Priv mode. For a detailed discussion of CLI commands,
refer to the CLI Guide.
