ESC 2000 LED Status Interface

The Led status interface is a serial interface converted to parallel by the hardware and driven to the
individual port status LEDs. Each port on both Switch A and Switch B have three status LEDs with
the following default settings:
• Link/Activity
• Duplex setting (full/half)
• Speed (10/100)
Due to the limitation on the number of LEDs that can physically be mounted on the ESC 2000, the
LED interface is mixed between the two switches. You can choose to display the status of either
Switch A or Switch B.
The following diagram shows the layout of the LEDs on the ESC 2000 which mounts as a daughter
card to the NIC.

Function
Used to connect to external indicators for major and minor alarms.
Common (C), normally closed (NC), and normally open (NO) contact
connections are provided. See
Can be used to connect to external sensors for system indication of up to
four alarm events (A,B,C,D).
Caution:
Voltage and current limitations. Do not connect to line level signals.
Illuminates green when power is applied to the slot or NIC.
Illuminates green when the module in the associated slot or NIC is
operating properly and no alarms or system faults exist.
Flashes yellow when a minor alarm is active for the slot or NIC,
accompanied by audible indication (beep). To reset, press the RESET
switch on the FCP.
Flashes red when a major alarm is active for the slot or NIC, accompanied
