Connecting Devices

This section describes how to connect devices to the switch module and includes the following topics:

Connecting Devices

• Installing and Connecting to Devices in the 10-Gigabit Ethernet Slots, page 3

• Connecting to 10/100/1000 Ports, page 3

• Verifying Port Connectivity, page 4

Installing and Connecting to Devices in the 10-Gigabit Ethernet Slots

The 10-Gb Ethernet module slots on the switch module are used for connections to other switches and
routers.

Use only Cisco-approved SFP+ or SFP modules with the switch module. Each Cisco module has an
internal serial EEPROM that is encoded with security information. This encoding provides a way for
Cisco to identify and validate that the module meets the requirements for the switch module. If the
validation fails, the software will not bring up the port.

Connecting to 10/100/1000 Ports

The External Management Port on the switch module is a 10/100/1000 Ethernet port that uses standard
RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The
100BASE-TX and 1000BASE-T traffic requires a Category 5, Category 5e, or Category 6 UTP cable.
The 10BASE-T traffic can use a Category 3 or Category 4 cable.

The autonegotiation feature is enabled by default on the External Management Port. At this setting, the
port configures itself to operate at the speed of attached devices. If the attached device does not support
autonegotiation, you can explicitly set the External Management Port speed and the duplex parameters.
To maximize performance, either allow the port to autonegotiate both speed and duplex, or set the port
speed and duplex parameters on both ends of the connection.

Configuring the Switch

Send feedback to [e-mail]

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is
enabled by default on the External Management Port. With auto-MDIX enabled, the port detects the
required cable type for copper Ethernet connections and configures the interface accordingly. Therefore,
you can use either a crossover or a straight-through cable for connections to the External Management
Port, regardless of the type of device on the other end of the connection.

For more information about enabling or disabling autonegotiation and auto-MDIX, see the Cisco Nexus

4001I and 4005I Switch Module for IBM BladeCenter NX-OS Command Reference and the Cisco Nexus
4001I and 4005I Switch Module for IBM BladeCenter NX-OS Configuration Guide on Cisco.com.

Verifying Port Connectivity

After you connect a device to a switch module port, the port LED is off while the switch module
establishes a link. This process takes about 30 seconds. The LED turns green when the switch module
and the attached device have an established link. If the LED is off, the device might not be turned on,
there might be a cable problem, or there might be a problem with the adapter installed in the device.

Configuring the Switch

This section describes how to configure the switch and includes the following topics:

• Assigning the IP Address on the switch module, page 4

• Initial Setup, page 6

Assigning the IP Address on the switch module

When you first set up the switch module, use the blade enclosure Advanced Management Module
(AMM) to enter the initial IP information. You can then access the switch module through the IP address
for further configuration.

Caution Do not connect devices to the external ports on the switch module until you have completed the setup

procedures and your configuration matches that of the upstream network.

To assign an IP address to the switch module, perform the following steps:

Step 1 Obtain the static IP address and the default gateway address from your system administrator.

Step 2 Establish a connection to the AMM, as described in the IBM BladeCenter Advanced Management

Module User’s Guide. In the login window, enter your User ID and password, and click Log In.

Note AMM refers to the switch module as the I/O module.

Step 3 In the Welcome window, click Continue.

The System Status summary pane appears.

Step 4 In the I/O Module Advanced Setup area, expand I/O Module Tasks and click Admin/Power/Restart (see

Managing the Switch

After you complete the initial switch module configuration, use the AMM, the CLI, or other management
options (if available) for further configuration. This section describes the following topics:

• Blade Enclosure Advanced Management Module, page 9

• Command-Line Interface, page 9

• Other Management Options, page 9

Blade Enclosure Advanced Management Module

For standalone switch module units, you can use the AMM to configure and manage the switch module.
See the IBM BladeCenter Advanced Management Module User’s Guide for more information.

Command-Line Interface

You can enter Cisco Nexus-OS commands and parameters using the command-line interface (CLI). You
can access the CLI by connecting your management station directly to the switch module console port
or by using Telnet from a remote management station.

Managing the Switch

For more information about using the CLI, see the Cisco Nexus 4001I and 4005I Switch Module for IBM
BladeCenter NX-OS Command Reference.

To connect to the switch module console port, perform the following steps:

Step 1 Connect a console cable to the front panel serial port and connect an Ethernet cable to the front panel

Ethernet management port.

Step 2 Start a terminal-emulation program on the PC.

Step 3 Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit and no

flow control.

Step 4 Telnet to the switch module by using the console or Ethernet management interface.

Provide the login and password that was configured in Step 3 of the “Initial Setup” section on page 6.

Step 5 Use the CLI to enter commands to configure and manage the switch module.

Other Management Options

You can access the Cisco Management Information Base (MIB) variables through SNMP. The SNMP
system consists of three parts: the SNMP manager, the SNMP agent, and the MIB. You can compile
Cisco MIBs with your network management software. If SNMP is configured on a switch, the SNMP
agent responds to MIB-related queries sent by the network management software.
