(4) LEDs (Light Emitting Diode) and Switches
The LED of a chassis indicates the action status of a fan unit, BCU, PSU and high port-density
PSU-integrated NIF.
The LED is attached to the fan unit, and the status indicated by the LED differs depending on
the type of a device or the position where the fan unit is installed.
As for the status indicated by the each LED of a chassis, see Table 1.1-3. Refer to the section
"1.3 Power Supply." "1.4 Basic Control Module (BCU)" or "1.6 Network Interface (NIF)" for the
LED and switches of other component units.

NOTE 1: When a high port-density PSU-integrated NIF is installed, its action status is shown here.
NOTE 2: When a high port-density PSU-integrated NIF is installed, and even though the LED status is "Green(blinking)",
the NIF will not be active in the following cases:
・
During a time span of approximately 10 seconds after the LED status becomes "Green(ON)" after GS4000 is powered on.
・
The "close nif" command is entered from an operation terminal.
・
The "disable" configuration command is entered from an operation terminal.
NOTE 3: For a high port-density PSU-integrated NIF, the "OFF" status of LED means that exchanging the NIF is possible.
