Hardware Features

10-Gigabit Ethernet Module Slot

The Catalyst Switch Module 3110X 10-Gigabit Ethernet module slot is used for an uplink connection to other switches and routers. The module slot operates in full-duplex mode and uses the hot-swappable Cisco X2 transceiver modules.

The X2 transceiver modules have a dual SC/PC connector (-SR, -LX4) or an Infiniband 4x connector (-CX4) for connections to multimode fiber (MMF), single-mode fiber (SMF), or 4x Infiniband cable.

These are the supported Cisco X2 transceiver modules:

•X2-10GB-SR

•X2-10GB-CX4

•X2-10GB-LX4

For information about installing a transceiver module, see the “Installing Devices in the 10-Gigabit Ethernet Slot” section on page 2-11. For cable specifications, see Appendix B, “Connector and Cable Specifications.”

Port Numbering

Table 1-2describes the switch module port numbering.

Table 1-2 Switch Module Port Numbering

Port	Description
Ports 1 to 141	Internal Gigabit Ethernet 1000BASE-X downlink ports that connect to
	the blade enclosure.
Ports 15 to 18 (Catalyst Switch	External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports.
Module 3110G and 3012)
Port 1 (X2) (Catalyst Switch	External 10-Gigabit Ethernet module slot.
Module 3110X)

1.The number of internal ports is determined by the blade enclosure model. See the blade enclosure documentation for more information about internal port numbering.

Internal 100BASE-T Ethernet Management Port

The internal Ethernet management port (Fa0) is used only for switch module management traffic, not for data traffic. It is connected to the IBM advanced Management Module (aMM) through the blade enclosure backplane connector. Traffic to and from this port is isolated from the switch module ports. This port only supports autonegotiation with 100 Mb/s and full-duplex mode.
