This will reboot the unit, taking up to 120 seconds. During this time you will not be able to
communicate with the unit.
If you cannot communicate with the unit after 120 seconds, this could indicate a problem with
the memory update process. Under these circumstances the user should enter “Recovery
Mode”, see Section
1127H
9.
After the reboot the user should check that the required software image is loaded and
running.
NOTE
: Please ensure that you are upgrading the correct units. Units cannot be downgraded
and license keys cannot be swoped once upgraded.
8.3.7 Spectrum Management
Spectrum Management Selection is the PTP 600 Series Bridge feature that monitors the
available wireless spectrum and directs both ends of the wireless link to operate on a channel
with a minimum level of co-channel and adjacent channel interference.
8.3.7.1 Wireless
Channels
The PTP 600 Series Bridge operates using a set of predefined overlapping channels. There
are a different number of channels, depending on the raster mode selected. Each channel
occupies 30 MHz, 15 MHz, 10 MHz or 5 MHz of wireless spectrum and is offset in center
frequency from its neighboring channel by 10 MHz or 6 MHz. It is important to note that
adjacent channels on the Spectrum management display have a 10 MHz or 6 MHz overlap to
the adjacent channel.
The default channelization can be modified by varying the lower center frequency attribute in
the installation wizard - see Section
1128H
8.3.4.4. See Section
1129H
5.5 and
1130H
5.7 for more detail.
