CSX7000 Guide20 CyberSWITCHThe power supply is contained in a canister type of enclosure to make the replacement as easy aspossible. (See Power Supply Installation for details.)Note that there are two LEDs on each power supply: one red and one green. When power is on, thegreen LED is lit to indicate a no-fault condition. If power is on and the red LED is lit, a problemexists. If power is off, the LEDs will not light.BACKPLANE BAYThe segmentable CSX7000 ISA backplane technology is based on the concept of joining or shuntinggroups of slots together. The backplane consists of eight groups of paired slots that are isolated: atotal of 16 slots. These paired slots can be electrically joined together with special shunt boardsinserted between the standard ISA slots.An ISA strain relief cross-bar runs across the top of the cards in the backplane. This bar is intendedto stabilize the backplane to avoid intermittent connections. This is especially valuable in cabinetor rack setups in which the unit may be pushed in and pulled out repeatedly.SAFETY LATCH- SECURE AND TIGHTENSCREW FOR POWER SUPPLY OPERATION.1 MIN.
