System Installation Installing the Other Plug-In Cards
a future date and have purchased the 135 Watt power supplies to support the load but do not
have a minimum load on the shelf to maintain the 5V regulation. The 8000-135W-LOAD card
is installed in a server slot and has five factory-installed straps to provide a 1.8 AMP load on
the 5 volt power rail. Each strap adds a .36 AMP load onto the shelf. To determine if your shelf
configuration meets the minimum requirement, see Section A.5.1 on page 16 to confirm the
5V load based on your individual card configuration.
2.8.5 Connecting Cables to the Cards
After inserting the cards into the system chassis, connect them to the external equipment,
using the proper cables. The cards have various types of connectors on their faceplate for those
connections.
Some cards have 50-pin Amphenol-type jacks on their faceplate. To connect a cable to this
type of jack, first plug the male connector of the cable into the jack and push it in all the way.
Then, tighten the mounting screws above and below the cable connector.
For modular (RJ-11 and RJ-48) jacks, push the cable’s mating plug into the jack until it snaps
into place. However, do not try to force the plug into the jack.
For DB-9 and DB-25 jacks, first plug the cable’s mating connector firmly into the jack. Then,
thread the screws on either side of the cable connector into the standoffs above and below the
card jacks, and hand-tighten them.
Refer to Appendix C. Pinouts in this guide for more information on the associated card jacks
and signal pinouts.
