4. Tighten the cable tie around the connector and trim the excess.
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 appropr iate
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.
