Removing an MX80 AC Power Supply

Before you remove a power supply, be aware of the following:

Note: The minimum number of power supplies must be present in the router at all times.

Caution: To maintain proper cooling and prevent thermal shutdown of the operating power supply unit, each power supply slot must contain either a power supply or a blank panel. If you remove a power supply, you must install a replacement power supply or a blank panel shortly after the removal.

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

To remove an AC power supply (see Figure 1):

1. Switch off the dedicated customer site circuit breaker for the power supply, and remove the power cord from the AC power source. Follow the instructions for your site.
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.
3. Move the AC input switch next to the appliance inlet on the power supply to the off (O) position.
4. Remove the power cord from the power supply.
5. Press the release latch on the left side of the power supply to disconnect the power supply from the chassis.
6. Pull the power supply straight out of the chassis.
