Upgrading the Line-Card Chassis Power Supplies


The required power supplies are standard in the T4000 router. To determine if you need to replace the power supplies in a T1600 router, see Hardware and Software Requirements for a T1600 Line-Card Chassis in a TX Matrix Plus Routing Matrix.

If needed, replace the power supplies. To replace the power supplies:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Replace the power supplies as required for the converted T1600 router. Use the standard replacement procedures described in the T1600 Core Router Hardware Guide.
