Install an Interface card in the UCx450

Do not operate the system without the cover for a duration exceeding five minutes.
It is recommended that you always use a static mat and static strap while working on components in the interior of the system.


Step One: Getting the UCx450 ready for card installation

  1. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
  2. Rotate the latch release lock counter clockwise to the unlocked position.
  3. Hold the cover on both sides, pressing your thumbs on the latch release lock and the indent, slide the cover toward the back of the system.
  4. Lift the cover away from the system.

Step Two: Installing the Interface (expansion) card

  1. Unpack the expansion card and prepare it for installation. For instructions, see the documentation accompanying the card.
  2. Locate the expansion-card connector on the riser.
  3. Lift and rotate the expansion-card latch and remove the filler bracket.
  4. Holding the card by its edges, position the card so that the card-edge connector aligns with the expansion-card connector.
  5. Align the expansion-card bracket with the hook on the chassis.
  6. Insert the card-edge connector into the expansion-card connector until the card is fully seated.
  7. Close the expansion-card latch.
Ensure that the expansion card is properly seated along the chassis, so that the expansion-card latch can be closed.

Step Three: Closing the System

  1. Place the cover onto the chassis and offset it slightly toward the back of the system so that it aligns with the notches and lays flush on the chassis.
  2. Slide the cover toward the front of the chassis until it locks in position.
  3. Rotate the latch release lock in a clockwise direction to secure the cover.
  4. Reconnect the system to the electrical outlet and turn the system on, including any attached peripherals.
  5. Once the UCX server is powered up, the new Interface Card will be automatically detected. See PSTN Cards in the Administration Guide for details.
