Netra 1290 LEDs

Use the LEDs on the individual system components to determine if the system is operating normally. That is, the LEDs should be routinely monitored on:

Boards (System Controller and I/O Assembly (IB_SSC), CPU/Memory, L2 Repeaters)
Fan trays
Power supplies

LEDs can be off or on. When the fault LED is on (lit), this indicates that a fault has occurred in the system. When the fault LED is lit, you should take immediate action to clear the fault.

Note: The green Power LED on a power supply will blink when the system is in Standby mode.

System LEDs

LED Name and Location	Color	Function
Locator	White	Normally off; can be lit by user command.
System Fault	Amber	Lights when the LOM detects a fault.
System Active	Green	Lights when power is applied to the system (that is, when the system is being powered on, or is powered on). Extinguished when the system is in Standby.
Top Access	Amber	Lights when a fault occurs in a FRU which can only be replaced from the top of the system.
UNIX Running	Green	Extinguished when a fault is detected and the system is not running correctly.
Alarm1 and Alarm2	Green	Light when triggered by events as specified in the LOM.
Source A and Source B	Green	Light when the relevant power feeds are present in Standby mode.

Fan LEDs

Fault

Lit when there is a fan fault or failure

CPU/Memory Board LEDs
Level 2 Repeater Board LEDs
I/O Board & System Controller (IB_SSC) LEDs
Main Fan Tray LEDs

LED Name	On	Off
Activated LED (green)	Device is activated	Device is deactivated
Fault LED (amber)	Internal fault	No internal fault.
OK to Remove (blue or amber)	Assembly can be removed	Assembly cannot be removed

Power Supply LEDs

LED Name	On	Off	Blinking
Activated LED (green)	Power Supply activated and operating normally	Power supply deactivated	Server is in Standby mode
Predictive Fault LED (amber)	Power supply detected a pending internal fault. Consider replacing power supply	Power supply fan speed is not below a specified minimum level	Power supply fan speed is below a specified minimum level
Fault LED (amber)	Fault present. Replace power supply	No fault present	n/a

Note: For power supplies, as long as a minimum of two power supplies are powered (with only the Power LED lit) one of the the other power supplies can be removed.

Disk Drive LEDs

LED Name	On	Off
Power (green)	Device is activated.	Device is deactivated.
Fault (amber)	Internal fault.	No internal fault.
OK to Remove (blue or amber)	Device can be removed.	Device cannot be removed.

Note: You can remove and install the hard drives without powering off the server. See Netra 1290 Server Service Manual for detailed steps.
