3.5.8 Connecting directly to a PC using the GC’s Ethernet port
The GC’s DHCP server feature and its Ethernet port on the backplane at J22 allow you to
connect directly to the GC. This is a useful feature for GCs that are not connected to a local
area network; all that is needed is a PC—typically a notebook computer—and a CAT5
Ethernet cable.
Note
The PC must have an Ethernet network interface card (NIC) that supports the automatic medium-
dependent interface crossover (Auto-MDIX) technology and either an Ethernet cable of at least CAT5
or an Ethernet Crossover Cable of at least CAT5.
Note
The GC can be connected (or remain connected) to the local network on TB11 on the backplane
while the DHCP feature is being used.
