Ethernet Uplink and Downlink Connectors
Ethernet UPLINK and DOWNLINK ports are provided in two forms: 8-pin modular
jacks, and sockets for Small Form-factor Pluggable (SFP) transceivers. 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.
Uplink and Downlink – 8-Pin Modular Jacks
The UPLINK and DOWNLINK wire connectors are
8-pin unkeyed modular jacks for 1000BaseT.
Uplink and Downlink – Cable Connectors
The UPLINK and DOWNLINK SFP sockets accept SFP transceivers compliant
with the SFP Transceiver MultiSource Agreement of September 14, 2000. The
SFP transceivers provide cable jacks for 1000BaseLX or 1000BaseSX
connections. See the specifications of your transceiver for more information.
