Monitoring the front operation panel

Location of LEDs

This chapter identifies the location of the various LEDs on your N7000 series
system and explains how to interpret LEDs for basic monitoring.
This chapter discusses the following topics:
v "Monitoring the front operation panel"
v "Monitoring the rear panel LEDs" on page 22
v "NVRAM6 adapter LEDs" on page 23
v "NVRAM6 copper-fiber converter LEDs" on page 24
v "Monitoring the power supply" on page 25
v "Monitoring the fans" on page 26
For information about error messages, troubleshooting, and monitoring the LEDs
for your N7000 series system and optional adapter cards, see the IBM System
Storage N series Platform Monitoring Guide.
For diagnostic information about your system, see the IBM System Storage N series
Diagnostics Guide.
The front operation panel has three LEDs, which indicate whether your system is
active and functioning normally or whether there are problems with the hardware.
You can also identify any hardware failure associated with the front operation
panel of the N7000 series system from the error messages displayed on your
system console.
Figure 5 shows the locations of the LEDs on the front panel of the N7000 series
system.
