When you insert a cable into the switch’s RJ-45 port, the switch automatically performs the following actions:
• Senses whether the cable is a straight-through or crossover cable.
• Determines whether the link to the attached device requires a normal connection (such as when you
are connecting the port to a computer) or an uplink connection (such as when you are connecting the
port to a router, switch, or hub).
• Automatically configures the RJ-45 port to enable communications with the attached device.The Auto
Uplink technology compensates for setting uplink connections while eliminating concern about whether
to use crossover or straight-through cables when you attach devices.
All RJ-45 copper ports on model GC728XP support Power over Ethernet (PoE+).
SFP and SFP+ Ports for Fiber Connectivity
To enable fiber connections on the switch, SFP and SFP+ fiber ports accommodate standard small form-factor
pluggable (SFP) gigabit interface converters (GBICs, also referred to as transceiver modules). GBICs are
sold separately from the switch.
The switch supports the NETGEAR SFP and SFP+ transceiver modules that are listed in the following table.

If you use a third-party passive direct-attach cable (DAC), the length of the cable must
not exceed 16.4 feet (5 meters).
