Connecting to workstations, servers, or routers
Straight-through UTP cabling is required for direct UTP attachment to workstations,
servers, or routers using network interface cards (NICs).
Fiber cabling is required for direct attachment to Gigabit NICs or switches and
routers through fiber ports. Refer to “Connecting a network device to a fiber port.”
Automatic MDI or MDIX detection
All 10/100/1000 Copper ports on the B24X devices support automatic Media
Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX)
detection. This feature is enabled on all Gigabit copper ports by default. For each
port, you can disable auto MDI or MDIX, designate the port as an MDI port, or
designate the port as an MDIX port.
For more information about this feature and how configure it, refer to the FastIron
and TurboIron 24X Configuration Guide .
Connecting a network device to a fiber port
For direct attachment from the device to a Gigabit NIC, switch, or router, fiber
cabling with an LC connector is required.
To connect the device to another network device using a fiber port, you must do the
following:
v Install a fiber optic module (SFP transceiver or mini-GBIC for Gigabit Ethernet
ports, or SFP+ transceiver for 10-Gigabit Ethernet ports)
v Cable the fiber optic module
The following sections provide information about performing these tasks.
Installing a fiber optic module: You must install a fiber optic module (SFP or
SFP+ transceiver) in each Gigabit Ethernet and 10-Gigabit Ethernet fiber port you
want to use.
You can install a new fiber optic module in a port while the device is powered on
and running.
To install a fiber optic module, you will need an ESD wrist strap with a plug for
connection to a metal surface.
CAUTION:
For safety reasons, the ESD wrist strap should contain a series 1 meg ohm
resistor.
Complete the following steps to install a fiber optic module:
1. Put on the ESD wrist strap and ground yourself by attaching the clip end to a
metal surface (such as an equipment rack) to act as ground.
2. Remove the new module from its protective packaging.
3. Gently insert the fiber optic module into the port until the module clicks into
place. The module is keyed to prevent incorrect insertion.
Cabling a fiber optic module: Complete the following steps to cable a fiber optic
module:
