24 Cable installation
Optional GBIC Ethernet uplink slot
The Model 3324 supports the use of one GBIC interface auto-link function. Normal Ethernet uplink port sta-
tus default is copper (RJ-45), but you can use the hot-swap capability—modules can be exchanged without
turning off power—of the Model 3324 to quickly change the uplink media to fiber.
GBIC fiber optics
A gigabit interface converter (GBIC) is a transceiver that converts electric currents (digital highs and lows) to opti-
cal signals, and optical signals to digital electric currents. The GBIC is typically employed in fiber optic and Ether-
net systems as an interface for high-speed networking. The data transfer rate is 1.25 gigabits per second (Gbps).
GBIC modules enable technicians to easily configure and upgrade electro-optical communications networks.
The typical GBIC transceiver is a plug-in module that supports hot-plugging. The devices are economical,
because they eliminate the necessity for replacing entire boards at the system level. Upgrading can be done with
any number of units at a time, from an individual module to all the modules in a system. GBIC is compliant
with the Gigabit Interface Converter Specification, Rev. 5.4 (MOD_DEF4) industry standard.
Connecting the EIA-574, RS-232 configuration port (DCE configured)
Install the supplied RJ-45-to-RJ-45 cable between the (2) DB9-RJ45 adapter and the RS-232 port (see figure 2
on page 15) and an open serial port on your computer. If you need to assemble your own cable, refer to the
pinout diagram in
figure 6 .
