296 Troubleshooting Your System

Troubleshooting a Network Switch Module

NOTE: To eliminate the possibility of a hardware problem with the module or its

attaching devices, first ensure that the module is properly initialized and

configured. See the Configuration Guide and the documentation that came with the

module before performing the following procedure.

Check that you have installed the module in an I/O slot that matches its

fabric type. See "Supported I/O Module Configurations" on page 51.

Check that the passthrough module or switch ports are cabled correctly.

A given mezzanine card in a full-height blade connects to two I/O ports on

the two associated I/O modules. See "I/O Module Port Assignments - Full-

Height Blades (not applicable to M610x)" on page 57.

Using the "17th blade" feature of the CMC, use the Connect Switch-X

command to verify that the switch is fully booted, and verify the switch’s

firmware revision and IP address.

Verify that the switch module has a valid IP address for the subnet. Verify

using the ICMP

ping

command.

Check the network connector indicators on the network switch module.

• If the link indicator displays an error condition, check all cable

connections. See "I/O Connectivity" on page 48 for the link indicator

error conditions for your particular network switch module.

• Try another connector on the external switch or hub.

• If the activity indicator does not light, replace the network switch

module. See "I/O Modules" on page 274.

Using the switch management interface, verify the switch port properties.

If the switch is configured correctly, back up the switch configuration and

replace the switch. See the switch module documentation for details.

If the blade requires a mezzanine card for a particular network switch

module, ensure that the appropriate mezzanine card is installed. If so,

reseat the mezzanine card. See "I/O Module Mezzanine Cards" on

page 198.

If the network link indicator on the blade is green, then the blade has a

valid link to the appropriate network switch module.

Ensure that the appropriate operating system drivers are installed and that

the protocol settings are configured to ensure proper communication.
