1–General Description Maintenance Panel

I/O blades (IO0–IO7), CPU blades (CPU0, CPU1), Power Supply blades (PS0, PS1), and the Fan blades (FAN0, FAN1) are identified based on where they are installed in the chassis. The Maintenance Panel (MP) is not removable and provides switch status and alternate access to the CPU blade LEDs and Ethernet ports.

Maintenance Panel

The Maintenance Panel provides a status interface for the switch and alternate Ethernet ports for the two CPU blades as shown in Figure 1-2. The chassis LEDs are as follows:

Chassis Good LED (Green)–This LED illuminates to indicate that switch is operational. This means that the primary CPU (CPU0) is functioning.

Chassis Power LED (Green)–This LED illuminates to indicate that at least one CPU blade is receiving power.

Chassis Beacon LED (White)–This LED and all other Beacon LEDs illuminate in response to a command issued from the management workstation to help locate a switch.

Chassis Fault LED (Amber)–This LED illuminates to indicate that a fatal error has occurred on one or more of the I/O blades, CPU, Power Supply, or Fan blades.

The CPU blade LEDs are described in “CPU Blades” on page 1-9.
