CK721-A Installation and Operation S300 Expansion Enclosures

In addition to total power consumption, the total number of connections should be
considered. The interconnect mechanism within the S300 expansion enclosure
requires looping a 5-conductor cable between modules. The voltage drop across this
cable network can affect the operation of an enclosure sub-system. To insure proper
operation, measure the +5VDC at each module on the 5-wire interconnect network.
The working range for +5V should be between +5.20 to +4.85. If a voltage drop,
between modules, is greater than 0.05VDC, the quality of the interconnect cables
should be checked.
