Chapter 1 Product Overview
Hardware Features
External 10-Gigabit Ethernet Module Ports
The Switch Module contains a switching ASIC that is capable of forwarding Ethernet and FCoE packets
at wire rate speed.
Six SFP+ ports are wired for external uplink access and are located on the front panel of the Switch
Module. These external uplinks support 10GBASE-SR SFP+, 10GBASE-LR SFP+, 10GBASE-CU
SFP+, and GE-SFP.
The port speed for the internal Ethernet ports can be set to 1 Gb or 10 Gb (only the internal Ethernet
ports can be set to auto-negotiate. See “
Internal 10-Gigabit Ethernet Module Server Ports
”). The duplex
setting must be full duplex.
For information on configuring the port settings, refer to the
Cisco Nexus 4001I and 4005I Switch
Module for IBM BladeCenter NX-OS Configuration Guide
and the
Cisco Nexus 4001I and 4005I Switch
Module for IBM BladeCenter NX-OS Command Reference
.
Serial Console Port
The Switch Module can be accessed through a serial console port located on the front panel. This is the
standard Cisco RS-232 console using an RJ45 connector for the Switch Module.
You can use the console port to connect the Switch Module to a host such as a PC, workstation, or a
terminal server. Use the supplied console cable to connect the switch module to a host.
For more information about the console port, refer to the
Cisco Nexus 4001I and 4005I Switch Module
for IBM BladeCenter Getting Started Guide
and the
Cisco Nexus 4001I and 4005I Switch Module for
IBM BladeCenter NX-OS Configuration Guide

Internal 10-Gigabit Ethernet Module Server Ports
The Switch Module contains a switching ASIC capable of forwarding Layer-2 packets at wire rate speed.
14 of the 10 Gb Ethernet ports are wired for internal access to the server blades. These downlink ports
connect to the server blades through the IBM BladeCenter chassis backplane, using the KX/KX4
interface.
The port speed for the internal Ethernet ports can be set to 1 Gb, 10 Gb, or auto-negotiate. However, the
duplex setting must be full duplex.
Note
The auto-negotiate speed mode works with network adapters that support IEEE802.3ap Clause 73, fixed
1G or fixed 10G. For network adapters that use the auto-negotiate speed mode, but do not support
IEEE802.3ap Clause 73, the switch port speed must be set to corresponding fixed speed of either 10 Gb
or 1 Gb.
