5.If you use an internal POTS splitter, repeat Step 1 through Step 4, substituting POTS 1–24 for DSL PORTS 1–24.

6.Secure the cables as required for strain relief.

GigE Uplink (Port 3)

Port 3 comprises two interfaces, only one of which may be used at a time:

￿An 8-position modular jack providing support for 1000BaseT

￿A Small Form-Factor Pluggable (SFP) socket providing, with the appropriate transceiver installed, support for 1000BaseX. A single-mode 1000BaseLX transceiver is available from Paradyne. See Appendix B, Equipment List.

Either interface can be used as the uplink for a single BitStorm 2600, or for the terminating unit in a stack of BitStorm 2600s.

Procedure

To use Port 3 as the uplink:

1.Connect the uplink cable to the BitStorm 2600:

—For a wire connection, plug the 8-position modular plug of your uplink cable into the Port 3 1000BT modular jack. A straight-through cable can be used regardless of the destination interface, since the port automatically distinguishes between a Medium-Dependent Interface (MDI) and an MDI Crossover (MDIX).

—For a fiber connection, plug your transceiver into the Port 3 GigE SFP socket. Plug the LC connector of your fiber optic uplink cable into the cable socket of the transceiver. Observing the minimum bend radius for your cable, fasten it with cable ties in such a way that it will not be kinked or snagged in the course of other cabling. If you do not know the specifications for your cable, maintain a radius of at least ten times the cable diameter.
