Smart-1 7000-L, Smart-1 7000-XL, and Smart-1 7000-UL

Smart-1 7000-L, Smart-1 7000-XL, and Smart-1 7000-UL Appliances have a redundant power supply unit (PSU) and support DC PSUs.

If necessary, you can replace a PSU. Note that all PSUs on an appliance must be of the same type (DC).

Warning:

  • To protect yourself and the appliance PSUs from electrostatic discharge, make sure that you are electromagnetically grounded before you install, uninstall, or replace a PSU.

  • We recommend that you use an ESD grounding wrist strap. Connect the grounding plug on the wrist strap to the appliance grounding point.

Warning - All work related to the DC power must be performed by trained and certified service personnel only.

Removing a DC Power Supply Unit

Before you remove a power supply unit, we recommend that you make sure that either:

  • A second DC power supply is installed and connected to a working power source.

    Or

  • The appliance is shut down.

To remove a power supply unit:

  1. Disconnect the power cable from the power source.

  2. Loosen the two screws on the PSU cable connector and then remove the DC power connector from the DC PSU.

  3. If the alarm sounds, press the Alarm Off button to the right of the DC PSUs.

  4. While you press and hold the PSU release lever, pull the extraction handle to remove the DC PSU.

Installing a Replacement DC Power Supply Unit

To install a replacement power supply unit:

  1. Make sure that both DC PSUs are the same type and have the same maximum output power.

  2. Insert the DC PSU into the power supply slot until it is completely seated and the release lever snaps into place.

  3. Connect the DC power connector to the DC PSU.

  4. Screw the two screws on the DC power connector.

  5. Plug the power cable into the power socket.

  6. Make sure that the power LED on the DC PSU is lit up.
