Evaluate Startup and Stop of PCI Modules

This section describes how to confirm the continuous system operation by failover after stopping the primary
CPU/IO module.
1. Check which is the primary CPU/IO module.
The CPU/IO module with the PRIMARY LED lit is the primary module.
2. Check whether the CPU/IO modules are duplicated.
To check if the CPU/IO modules are duplicated, see the System FT LED.

(2) DISK ACCESS LED
(3) System FT LED
*Each number in the table corresponds to the numbers in the above figure.
DISK ACCESS LED (2) is lit when there is access to the hard disk drive.
