I/O Blades

Transceivers and 10-Gbps Stacking Cables
SFP and X2 transceivers convert electrical signals to and from optical laser
signals to transmit and receive. SFP transceivers plug into the SFP ports; X2
transceivers plug into the X2 ports. Duplex fiber optic cables plug into the
transceivers, which then connect to the devices. An SFP port is capable of
transmitting at 8-Gbps, 4-Gbps, 2-Gbps, or 1-Gbps depending on the I/O blade
type; however, the transceiver must be capable of delivering at the desired rate.
10-Gbps ports transmit at 12.75-Gbps.
SFP and X2 transceivers are hot pluggable. This means that you can remove or
install a transceiver while the switch is operating without harming the switch or the
transceiver. However, communication with the connected device will be
interrupted. Refer to “Replacing Transceivers and Stacking Cables” on page 5-3
for information about installing and removing transceivers.
10-Gbps stacking cables are available to connect the QLogic 9000 Series switch
to other QLogic switches using the X2 ports.
An X2-XPAK stacking cable connects a QLogic 9000 Series switch and a
QLogic 5000 series switch.
An X2-X2 stacking cable connects two QLogic 9000 Series switches. Refer
to “HyperStacking” on page 3-29 for information about connecting
QLogic 9000 Series switches through the high bandwidth Inter-Chassis
connectors.
