Symbols or text Meaning
The CMU configured as Secondary will become
the inactive unit unless the Primary unit develops
a fault. In the case where the two ODUs at an end
have a different path loss, for example where they
are coupled to a common antenna using an
Asymmetric Coupler Mounting Kit (see Coupler
mounting kits on page 1-30) , the CMU configured
as Secondary should be connected to the RFU
with the highest path loss.
For IRFUs, the CMU configured as Secondary
should always be connected to the right hand
transceiver.
The IP address of the unit being browsed.
The IP address of the unit.
These units are active (Tx Hi and Tx Lo). Active
units are the units which radiate at the antenna
and forward traffic between the wireless interface
and the Ethernet ports. The black line represents
the link between active units.
These units are inactive (Tx Hi and Tx Lo).
Inactive units remain on standby waiting to take
over the active role in case of a fault. They do not
radiate or forward traffic between the Wireless
interface and the Ethernet ports.
These units are not protecting the active unit.
They may be faulty or configured in a way which
is not protecting the active unit. Roll the mouse
over the icon to see the reason why the unit is not
protecting.
The unit being browsed cannot communicate with
a unit identified in this way. This may be because
the unit is powered down or the protection cable
is not connected.
If both units at the end remote from the end being
managed are gray, this indicates that the wireless
link is down.
