5.5.1
Network ports
4E-SW6 offers 2 L-Net ports (RJ-45) for network connections to C500 main unit and distributed
parts of the 4EVAC Voice Evacuation System. Both L-Net ports are equal, therefore it makes no
difference which port is connected to which side of L-Net daisy-chain.

5.5.2
Redundant link
If you need to make redundant L-Net connection to Compact 500 main unit, connect both L-Net
ports of the device to two L-Net ports on the C500 main unit. You can choose any L-Net port on
the C500 main unit. This creates double daisy-chain of redundant A/B power and data link to the
device and ensures fail-safe networking in case of single cable or port failure.
Both spurs of the redundant A/B link may be populated with other L-Net devices.
NOTE:
The device is equipped with a power link jumper, by default in CLOSED position
(pass-through power over L-Net). In order to create redundant link, the jumper must be
moved in OPEN position. The device will be then immune to a single port short-circuit of power
bus.
