Boot Firmware Source
WirelessTaps may come with a local firmware option installed. In this case, runtime
firmware is stored in non-volatile memory, and the WirelessTap can function without a
backhaul interface. This generally not useful, and is seen mostly in demonstration and

relatively rare.
In any case, if you do have a WirelessTap so equipped, you may desire to monitor the boot
sequence via the console port and terminal. There are boot options that you may want to
select. The most common are to use the Ethernet interface as the backhaul, use the
select. The most common are to use the Ethernet interface as the backhaul, use the
DOCSIS interface as backhaul, or use “No Network” backhaul. The first two must have
DHCP available, whereas the “No Network” option does not. Please see the Systems
Administrator Guide for more details.

Please Note: Even with the local firmware option installed, the WirelessTap is almost
certainly configured to search for boot firmware via the DOCSIS Interface first, then the

Initial Testing
The console port can be used to quickly check the platform’s operational status. Simply
connect a terminal set to 115.2K N81 using a null modem cable. If the server is running
and stable you will see only a login prompt. If the unit cannot find a boot file to execute it
and stable you will see only a login prompt. If the unit cannot find a boot file to execute it
will continually try by restarting itself every few minutes. You will be able to witness this via
the console. The WirelessTap unit also beeps though it may be difficult to hear in noisy

Radio testing can be accomplished in a number of ways. One is to use a specialty tester
such as the YellowJacket handheld tester (for 802.11 systems
). Another is a home-brew
test setup such as a laptop running NetStumber, Kismet or other such software application
(using an appropriate wireless adapter). You should be able to see the radios in the display
window. Please consult the appropriate guide. Beware using Windows based laptops and

Please consult the appropriate guides, but we suggest using test gear for testing purposes.
Other test rigs can be used, such as vector signal analyzers, spectrum analyzers and RF
power meters, but these require exceptional skill given the complex modulation and time
