How To Replace the Power Supply

Installing a New Power Supply

Warning

Do not touch any of the exposed leads, terminals, or components. Hazardous voltages, capable of
causing death, may be present in this product.

Step 1

Remove the new power supply from the antistatic bag.

Step 2

Insert the bottom edges of the power supply into the rail guides in the power supply bay. If you can tilt
the power supply more than 2 degrees after it is in the power supply bay, both edges are not in the rail
guides.

Step 3

Slide the power supply into the power supply bay until it stops.

Note

Insert the power supply with a single, steady motion. Bouncing the power supply during
insertion may cause an alarm condition in the Cisco MeetingPlace system.

Step 4

Use a Phillips screwdriver to replace the two captive screws that secure the power supply to the
Cisco MeetingPlace 8112 chassis. These screws are located at the bottom of the power supply.

Verifying that the New Power Supply Works Correctly

Step 1

Check the LEDs. See the

“Determining the Status of the Current Power Supplies By Scanning the LEDs”

section on page 3

. If the LEDs do not look normal , try reseating the power supply. See

Step 3

Step 2

Enter hwconfig. See the

“Determining the Status of the Current Power Supplies By Using Telnet”

section on page 3

. If the hwconfig output does not look normal , try reseating the power supply. See

Step 3

Step 3

If you reseat the power supply and still have problems, examine the power supply connectors to see if
they are damaged or dirty. If both sides of the connectors look good, try installing another power supply.

If the second power supply installs and works correctly, send the power supply you tried to use as a
replacement first back to the factory. If the second power supply does not install or work correctly,
contact Cisco TAC.
