Tools Needed:
A #3 Phillips screwdriver - recommended magnetic with 6" minimum shaft. A 12-16" works best on this system.
Optional: A small diameter (1/8", 3/32" or 2 to 3mm, approximately 36" or 1M long) dowel or fish stick would assist with cable replacement.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

1. Follow safety and ESD precautions.

2. Remove the status LED panel. Also remove the cosmetic cover(s) between the LED panel down to and including the cosmetic cover of the switching needing service.
If needed, refer to How to Replace an NMS (Netra Modular System) Status LED Panel (Alarm Panel) (Doc ID 2050227.1)

3. Remove the coupler panel from the RETMA rails, leaving the cables connected, if possible.

4. Remove the fiber tray, if it is blocking the power cord.

5. Disconnect the faulty power cord from the switch. Work the power cable up to the top of the rack above the switches so that it doesn’t get lost or trapped in the side of the rack.

6. Remove the faulty power cord from the rear of the modular system.

7. Connect the replacement power cord to the switch.

8. Connect the replacement power cord to the PDU, routing it around the RETMA rails (same as the other switch power cords).

9. Verify that the switch now has power on the replacement cord and associated PSU.

10. Install the fiber tray, coupler panel, and LED panel. Replace all cosmetic covers removed earlier in step #2.
