    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

cisco Appliance Light Path Diagnostics #ISE #NCS #PRIME 

My Cisco appliance was showing the amber color exclamation point. While I did the typical show and tech commands I could not find anything wrong with the box. I checked the Light Path Diagnostics on the appliance, it quickly pointed out a power supply problem.

Figure 1-4 shows the LEDs and controls on the light path diagnostics panel.

Light Path Diagnostics Panel Components

Remind button: This button places the system-error LED on the front panel into Remind mode. In Remind mode, the system-error LED flashes once every 2 seconds until the problem is corrected, the NCS appliance is restarted, or a new problem occurs.

By placing the system-error LED indicator in Remind mode, you acknowledge that you are aware of the last failure but will not take immediate action to correct the problem.

NMI button: This button is used to force a nonmaskable interrupt to the microprocessor. This button is not currently used by the Cisco Prime Network Control System appliance. Press this button only when directed by the Cisco TAC personnel.

Checkpoint code display: This display provides a checkpoint code that indicates the point at which the system stopped during the boot block and POST. A checkpoint code is either a byte or a word value that is produced by UEFI. The display does not provide error codes or suggest components to be replaced.

Reset button: Press this button to reset the NCS appliance and run the power-on self-test (POST). You might have to use a pen or the end of a straightened paper clip to press the button. The Reset button is in the lower-right corner of the light path diagnostics panel.

 

Table 1-3 Light path diagnostics panel LEDs 

Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
LED
Description
Action

None, but the system error LED is lit.

An error occurred and cannot be isolated. The error is not represented by a path.

Contact Cisco TAC for assistance.

OVER SPEC

The power supplies are using more power than their maximum rating.

Contact Cisco TAC for assistance.

LOG

An error occurred.

Contact Cisco TAC for assistance.

LINK

Reserved.

-

PS

Power supply 1 or 2 has failed.

1. Check the power supply that has a lit amber LED (see Power-supply LEDs).

2. Make sure that the power supplies are seated correctly.

3. Remove one of the power supplies to isolate the failed power supply.

4. Replace the failed power supply.

PCI

An error has occurred on a PCI bus or on the system board. An additional LED is lit next to a failing PCI slot.

Contact Cisco TAC for assistance.

SP

A service processor error has been detected.

1. Shut down the system and remove the power cords from the NCS appliance; then, reconnect the NCS appliance to power and restart it.

2. If the problem does not go away, contact Cisco TAC for assistance.

FAN

A fan has failed, is operating too slowly, or has been removed. The TEMP LED might also be lit.

Contact Cisco TAC to replace your Cisco Prime Network Control System appliance and for further assistance.

TEMP

The system temperature has exceeded a threshold level. A failing fan can cause the TEMP LED to be lit.

Contact Cisco TAC for assistance.

MEM

When only the MEM LED is lit, a memory error has occurred. When both the MEM and CNFG LEDs are lit, the memory configuration is invalid or the PCI Option ROM is out of resource.

Contact Cisco TAC for assistance.

NMI

A nonmaskable interrupt has occurred, or the NMI button was pressed.

Check the system-error log for information about the error.

Contact Cisco TAC if further assistance is needed.

CNFG

A hardware configuration error has occurred.

Contact Cisco TAC for assistance.

CPU

An invalid microprocessor configuration or a microprocessor has failed (both the CPU LED and the CNFG LED might be lit).

Contact Cisco TAC for assistance.

VRM

Reserved.

-

DASD

A hard disk drive has failed or is missing.

1. Check the LEDs on the hard disk drives for the drive with a lit status LED and reseat the hard disk drive.

2. If reseating the drive does not resolve the issue, then the failed hard disk drive must be replaced. Contact Cisco TAC for assistance.

RAID

Reserved.

-

BRD

An error has occurred on the system board.

Contact Cisco TAC for assistance.
