Maintaining the PTX3000 Chassis

Routine Maintenance Procedures for the PTX3000

Purpose

For optimum performance, perform preventive maintenance procedures.

Action

On a regular basis:

  • Inspect the installation site for moisture, loose wires or cables, and excessive dust. Make sure that airflow is unobstructed around the PTX3000 and into the air intake vents.

  • Check the status-reporting devices on the craft interface: system alarms, LEDs, and the craft interface display.

  • Inspect all air filters in the PTX3000, replacing them every 6 months. Do not run the PTX3000 for more than a few minutes without all the air filters in place.

Tools and Parts Required to Maintain the PTX3000 Components

To maintain the hardware components, you need the following tools and parts:

  • ESD grounding wrist strap

Replacing a PTX3000 Craft Interface

Removing a PTX3000 Craft Interface

The craft interface is located below the air filter and to the left of the SIBs. The craft interface weighs 0.4 lb (0.2 kg). It is hot-insertable and hot-removable.

To remove the craft interface (see Figure 1):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Loosen the captive screw on the craft interface, using a number 1 Phillips (+) screwdriver.
  3. Grasp the craft interface, and slide it out of the chassis.

Installing a PTX3000 Craft Interface

To install the craft interface (see Figure 2):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Grasp the craft interface, and press it into the chassis.
  3. Tighten the captive screws on the craft interface, using a Phillips screwdriver, number 1.
Note:

After you install the craft interface in an operating PTX3000, allow several minutes for the LEDs on the craft interface to reflect the current state of the PTX3000.
