Removing a DC Power Supply

The power supplies are located at the rear of the chassis. Each DC power supply weighs approximately 3.8 lb (1.7 kg).

CAUTION: Do not leave a power supply slot empty for more than 30 minutes while the router is operational. For proper airflow, the power supply must remain in the chassis or a blank panel must be used in an empty slot.

NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on.

To remove a DC power supply, follow this procedure:

1.Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cables might become active during the removal process.

2.Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see the MX960 Ethernet Services Router Hardware Guide.

3.Switch the circuit breaker on the power supply faceplate to the OFF position.

4.Remove the clear plastic cover protecting the terminal studs on the faceplate.

5.Remove the nuts and washers from the terminal studs (see Figure 2 on page 5). (Use a 3/8–in. nut driver or pliers.)
