Servers are numbered by their position in the chain (1 through n ). If one appliance
server is removed from the chain, all successive appliance servers are renumbered.
For example, if the twelfth appliance server is removed from a chain of 15 appliance
servers, appliance servers 13 through 15 will then be renumbered to 12 through 14.
When removing or replacing appliance servers, or changing cables in the chain, it is
possible for more than one Select LED to be illuminated on the appliance servers in
the chain. To clear all but the selected appliance server LED, press the Select button
on any one of the appliance servers in the chain.
If you are using a flat-panel monitor, you might need to adjust the image lock on your
monitor when multiple appliance servers are connected using C2T interconnect
cables. To adjust this image, select one of the middle appliance servers in the chain
by pressing the Select button on the front of the appliance server; then, adjust the
image lock accordingly. For more information on how to adjust the image lock, see
the documentation that comes with your flat-panel monitor.
Note: For the chain to operate properly, no more than two adjacent appliance servers
can be unplugged from the electrical outlet at the same time.
Cabling the model 8672 appliance server
Use the following illustration to cable the model 8672 appliance server.
Figure 25. Locating the connectors
To effectively manage the cables on your appliance server, keep groups of cables
secured together, and do not run cables across the back of the appliance server.
Notes:
1. Use cable straps to bundle like cables together.
2. Use cable straps to secure the cable bundles to the vertical rails of the rack
cabinet.
3. When possible, separate data and power cables. For more information on cable
routing, see the cabling instructions for your xSeries 130 server on the World
Wide Web at http://www.pc.ibm.com/support.
4. Do not secure cables too tightly. Overtightening can cause internal damage to
your cables.
Refer to “Input/output connector locations and ports” on page 74 for more details
about the input/output connectors on your appliance server.
