1–General Description CPU Blades

Maintenance Button

The Maintenance button is a dual-function momentary switch on the CPU blade. Its purpose is to reset a CPU blade or to place the switch in maintenance mode. Maintenance mode is used to recover the switch when flash memory or the resident configuration file is corrupted. Refer to “Recovering a Switch Using Maintenance Mode” on page 4-15for more information about using maintenance mode.

Resetting a CPU Blade

To reset a CPU blade, use a pointed tool to momentarily press and release the Maintenance button on a CPU blade.

Placing the Switch in Maintenance Mode

Maintenance mode removes power from the I/O blades, and temporarily sets the switch IP address to 10.0.0.1. To place the switch in maintenance mode, isolate the switch from the fabric, then do one of the following:

For a single CPU blade switch:

1.Using a pointed tool, press and hold the Maintenance button.

2.When the CPU blade Heartbeat LED illuminates steady, release the Maintenance button.

For a dual CPU blade switch:

1.If there are two Ethernet connections, disconnect one of them.

2.Power down the switch.

3.Power up the switch. As the switch is powering up, using two pointed tools, press and hold the Maintenance buttons on both CPU blades at approximately the same time. When the CPU blade Heartbeat LED illuminates steady, release the Maintenance buttons.

To exit maintenance mode and return to normal operation, do the following:

For a single CPU blade switch, momentarily press and release the Maintenance button, or power cycle the switch.

For a dual CPU blade switch, power cycle the switch.
