Article ID: KB11660 KB Last Updated: 27 Mar 2020Version: 4.0
Summary:
What are the status and alarm indicators on IDP sensors for 75, 250, 800, and 8200 sensors.
Solution:
IDP Sensor LEDs listed here are for the following IDP sensor components:
 System status
 Management and high availability ports
 Traffic ports
 Hard drives
 Power supply (back panel)
 
System Status LEDs
The IDP 75, 250, 800, and 8200 sensors each have three system status lights on the front panel to indicate power, hard drive activity, and overheating.

Management and High Availability Port LEDs
  • Management and high availability (HA) ports each have two LEDs:   LINK and TX/RX.
  • Management ports are on all sensors.
  • HA ports are available on the IDP 250, 800, and 8200 sensors only.

Front Panel System Status LEDs
Color   Function LED Action Status Description
Green Power Stays on when powered on.
Stays off when powered off.
Yellow Hard Drive Activity Flickers with activity
Red Fault Blinks slowly when a fan fails
Blinks quickly when system is overheated.
Stays on when the power supply fails.
Stays off when the system is functioning at a normal temperature.


LEDs for Management and HA Ports
Traffic Port LEDs
The IDP 75, 250, 800, and 8200 sensors each have two traffic status LEDs on each traffic port.
 
Port Description Status
LINK Port connection/activity indicator. Blinks amber to indicate activity on the port.
TX/RX Speed indicator. Stays off for 10 Mbps.
Glows green for 100 Mbps.
Glows amber for 1000 Mbps.
 
IDP Sensor Traffic Port LEDs         
Indicator Location  
Speed/Description
Link Activity - Left LED Green Stays on when there is a link.
LED Stays off when there is no link.
Blinks when there is activity.
Link Speed - Right LED None 10 Mbps
Green 100 Mbps
Yellow 1 Gbps
Orange 10 Gbps


Hard Drive LEDs on Front Panel
The front panel of the sensors provide access to hard disk drives for 800 and 8200 sensors only.
 
Hard drive failure (800 and 8200 only)
  • The left LED on the hard drive. The LED is off if the hard drive is functioning normally. The LED is red if the hard drive has failed. In addition, the system emits a high-pitch noise if a hard drive has failed.
  • The LED flashes red if the drive is being rebuilt. Do not turn the power off, unplug the unit, or remove either drive while the drive is being rebuilt.

Hard drive activity (800 and 8200 only)
The right LED on the hard drive. The LED flashes green to indicate hard drive activity.

Power Supply LEDs on Back Panel
The back panel of the sensors provide access to power supplies on the 800 and 8200 sensors only.


IDP Sensor Power Supplies
  • IDP 75 - One fixed power supply.
  • IDP 250 - One removable power supply.
  • IDP 800, 8200 -  Two removable hot-swappable power supplies.
    • Both sensors are shipped with the AC power supply.
    • The DC power supplies are optional as FRUs.

    Power Supply Status (800 and 8200 only)
    • The LED is located on the power supply above the plug socket. It glows amber to indicate that the power supply is receiving power. It glows green to indicate that the power supply is powering the unit.
    • If a power supply has failed, or is not receiving power, the system emits a high-pitched whine.
