Installing or Replacing SBus Cards

If you are replacing an SBus card in the Netra 150 server, first go to "Removing an SBus Card ", then return here.

Installing an SBus Card

1. Place the SBus card on an antistatic surface.

2. If required, set the jumpers or switches on the card.

   See your SBus product documentation.

3. Remove the SBus card extractor (if any).

   1. Bend one leg of the extractor slightly to the outside until the hook clears the hole in the SBus card (Figure 2-13).

   2. Remove the other side of the extractor.

      It should come out easily without being bent.

4. Locate the SBus slot in which you want to install the card.

   The Netra 150 system board has three SBus slots. See Figure 2-14 for the location of each SBus slot.

5. Slide the card at an angle into the system unit by hooking the card backplate under the two tabs on the back panel (Figure 2-15).

   Be sure the card backplate shows through the slot on the back panel.

6. Align the connector with the SBus socket. Gently press the corners of the card to push the connector into the socket.

   Do not force the card, or you may damage the pins on the card. If the SBus card is located in SBus slot 0 or 1, see Figure 2-16. If the SBus card is located in SBus slot 2, see Figure 2-17.

7. Lock the card retainers.

   • If the SBus card is located in SBus slot 0 or 1, push the rear card retainers forward over the edge of the SBus card. See Figure 2-16.

   • If the SBus card is located in SBus slot 2, push the card retainer down.

   See Figure 2-17. There is only one card retainer for the SBus slot 2.
