1. Install the rack interconnect cable before installing the power supply in
multiple rack configurations.
2. The cables are “keyed” for proper installation. The end of the cable that
plugs into the left socket has the “key” on the outside of the connector. The
opposite end of the cable has the “key” on the inside of the connector.
Figure 1 displays the connector and the keys.
3. Make sure the cable is properly secured to prevent against the effects of
shock and vibration. To remove the cable, move the tabs on the socket
outward and the connector will pop out. See Figure 1 on the next page.
Refer to the
SLC 500™ Modular Hardware Style Installation and
Operation Manual
, publication 1747-6.2, for complete information.
4. The expansion cable must always exit the right end of the rack with the
CPU. Figure 2 displays correct and incorrect installations.
5. The 1746-C16 cable should be used when connecting two 1746-A13 racks
(one above the other) with 1746-P4 power supplies.
