3. Insert the cable connector (a tab on each connector should face up) into the port connector or

until the tab locks into place.

Cleaning fiber optic modules

To avoid problems with connections between fiber optic modules (SFP (mini-GBIC), SFP+, or XFP)

and the fiber cable connectors, it is strongly recommended that you clean both connectors each

time you disconnect and reconnect them. Refer to “Cleaning the fiber optic connectors” on

page 105.

Automatic MDI or MDIX detection

All 10/100 and Gigabit Ethernet copper ports on FastIron devices support automatic Media

Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This

feature is enabled on all 10/100 and Gigabit copper ports by default. For each port, you can

disable auto MDI or MDIX, or designate the port as an MDI port, or an MDIX port.

For more information about this feature refer to the FastIron Configuration Guide.

Using a CX4 transceiver

A twin-axial 10G copper CX4 XFP transceiver can be installed in any 10G port. For a link to operate

properly, both sides must use identical CX4 transceivers. Refer to Figure 43.

The CX4 transceiver requires a 15 meter CX4-grade cable with 24 or 26 American Wire Gauge

(AWG). This cable can be purchased from Brocade. Refer to part number CAB-CX4-0050 when

ordering. Refer to Figure 44.

NOTE

The CX4 transceiver is not hot-swappable.
