Downlink GigE Connectors
There are two DOWNLINK GigE connectors on the unit. Only one can be active.
For the wire connection, either a straight-through or a crossover cable can be
used. The wiring is automatically detected and, if necessary, compensated for.
A DOWNLINK GigE connector can be used to connect to:
An adjunct server to provide caching, video on demand, or gateway services
The UPLINK GigE connector of a downstream BitStorm 4800 (see
Procedure
To attach an adjunct server:
1. Determine the interface type to be used (wire or fiber), and procure the
appropriate copper cable, or fiber optic cable and SFP transceiver.
2. For a wire connection, plug the 8-position modular plug into the DOWNLINK
GigE modular jack.
3. For a fiber connection, plug your transceiver into the DOWNLINK GigE SFP
socket. Plug your fiber optic cable into the cable socket of the transceiver.
4. Connect the other end of the cable to your adjunct server.
