General - Netra 240 LEDs

Netra 240 LEDs

The server has LED indicators associated with the server itself and with various components. The server status indicators are located on the bezel and are repeated on the back panel. The components with LED indicators to convey status are the dry contact alarm card, power supply units, Ethernet port and hard drives. Details on the network link indicators and the network speed indicators are also provided.

Front Panel LEDs

This figure shows the location of the front panel indicators. They are the four dry contact alarm card indicators and the three server status indicators.

^{1
- NC state is the normally closed state. This state represents the default
mode of the relay contacts in the normally closed state.}

^{2
- NO state is the normally open state. This state represents the
default mode of the relay contacts in the normally open state.}This table contains details on the alarm indicators and dry contact alarm states. It has sixteen rows and nine columns.

^{3
- The implementation of this alarm indicator state is subject to
change.}

^{4
- The user can shutdown the system using commands such as init0
and init6. This does not include
the system power shut down.}

^{5
- Based on a determination of the fault conditions, the user
can turn the alarm on using the Solaris platform alarm API or ALOM
CLI. For more information on the alarm API see the Netra
240 Server System Administration Guide (part no. 817-2700-xx)
and for more information on ALOM CLI see the Sun
Advanced Lights Out Manager Software User's Guide for the Netra
240 Server (part no. 817-3174-xx}

In all cases when the user sets an alarm, a message is displayed on the console. For example, when the critical alarm is set, the following message is displayed on the console: Note that in some instances when the critical alarm is set, the associated alarm indicator is not lit. This implementation is subject to change in future
(see Footnote ^[3]).
