Resolving The Problem

Note: Nortel Networks Layer 2/3 GbE Switch Module (GbESM) for IBM BladeCenter

To begin troubleshooting, check the following top issues. If your issue is listed, select the link, otherwise proceed to step 2.

	Nortel Layer 2/3 Copper and Fiber GbESM technical update
	Nortel Layer 2/3 Copper GbESM product overview
	Nortel Layer 2/3 Fiber GbESM product overview

Download the latest firmware and software code updates for your system:

	Download Nortel Networks Layer 2/3 GbESM firmware
	Download the latest BladeCenter support software

Note: Whenever you do a firmware update followed by a restart, first check to see if you have 'Preserve new IP configuration on all resets' Enabled. If this function is not enabled, an incorrect IP address could be set in the GbE Switch Module. This would stop all communication between the Management Module and the GbE Switch Module. Always backup the switch configuration before updating the switch's firmware.

Consult the product documentation for the Nortel Networks Layer 2/3 GbE Switch Module:

	Comparison of Layer 2/Layer 3 Functionality (White Paper)
	Alteon OS 21.0 Application Guide
	Alteon OS 21.0 BBI Quick Guide
	Alteon OS 21.0 Command Reference
	Alteon OS 21.0 Installation Guide
	Alteon OS 21.0 Release Notes

Nortel switches use the AlteonOS Web GUI for management:
1. Initial setup is performed via MM interface:
  - Configure IP address
  - Enable external ports (disabled by default)
2. Management is performed using telnet or http directly to the switch:
  - Configure the switch
  - Gather the switch log
  - Upgrade switch firmware (TFTP only)
  - Download and upload switch configuration (TFTP or browser)
3. The internal ports to blade servers are fixed at 1000Mbps. The four external ports are set for auto-sensing. The two ports to the BladeCenter MMs operate at 100Mbps. There is a serial console port on the front of the switch that can also be used to manage the switch. The switch supports a range of features for LAN configuration and management including link aggregation, VLANs, STP, and failover.
If these steps have not solved your problem:
Refer to your system's Hardware Maintenance Manual, or refer to "Need more help?"
