connect ports of the switch and the router.
The HD 8 Bypass Unit includes connectors for up to 4 links on the SG-9100. In
addition, the HD 8 Bypass Unit includes two D-type 9-pin connectors (DB-9) for
connection to the SG-9100 via special DB-9/USB cables (available from Allot).
An HD 8 Bypass Unit supports up to 8 ports (4 links).
The HD 8 Bypass Unit is a passive optical device with no need for external power
connection. It is powered by the SG-9100 as long as it is Active. It will move
automatically to bypass mode when SG-9100 is powered off, or by being forced to
bypass mode as protective action is taken. There is no way to have a single link go into
bypass independently. When moving to Bypass mode
all
links are switched into
Bypass.
NOTE
1G Copper interfaces must be enabled via CLI command. See
Configuring the SG-9100 for more information.
1G Copper interfaces may only use the 8 Port Bypass Unit is
available, limiting the number of ports which may be used on
the SG-9100.
