Connecting to the Interface Ports

Connecting to the Interface Ports
The Supervisor Engine III G has two GBICs with 1000BaseSX MMF connectors, 1000BaseLX/LH
MMF and SMF connectors, or 1000BaseZX connectors (see Figure 5).
The 1000BaseSX MMF, 1000Base LX/LH MMF and SMF, and 1000BaseZX ports operate in
full-duplex mode only.
For information on interface cables and equipment, such as Ethernet transceivers, refer to the
Catalyst 5000 Series Supervisor Engine Installation Guide.
1000BaseSX, 1000BaseLX/LH, and 1000BaseZX (Single-Mode or Multimode
Fiber-Optic Connectors)
Use SC fiber-optic connectors (see Figure 5) to connect to the 1000BaseSX, 1000BaseLX/LH, and
1000BaseZX ports. Always keep caps and plugs on the fiber-optic connectors on the cable and the
switch when they are not in use.
Warning

Connecting Gigabit Ethernet Modules
Supervisor Engine III G has Gigabit Ethernet ports that you can configure with any combination of
GBICs. A GBIC, shown in Figure 6, is a hot-swappable input/output device that plugs into the
module, linking the module with the fiber-optic network. GBIC types are listed in Table 4.
