RAM (or NVRAM). Lithium batteries are not customer replaceable. If they are mishandled there is a danger that they may explode. Always consult Meiko if you suspect that the battery needs replacing. Never dispose of lithium batteries in a fire or attempt to dismantle. - Page 9 When using the Genie fork lift you must first attach the two lift-clamp assemblies to either side of the module. Unscrew the securing screw that holds the telescopic section of the lift-clamp closed. Insert the rear locating pins into the holes at the rear edge of the module (the open end of the box section should face the front of the module).

Page 11: Overview
Overview The Processor Module is a physical enclosure for up to 4 processor boards. Sup- porting infrastructure within the module consists of cooling fans, power supply, and connections to the CS-2 data network, the CS-2 control network, and exter- nal SCSI peripheral buses. Up to 4 SCSI disk devices may also be fitted within the module and connected to the processor boards in one of three standard con- figurations (all disks connected to one board, two disks to each of two boards, or one disk per board). - Page 12 S1002–10M128.02...

Page 17: Installing The Processor Module
Installing the Processor Module You must read this chapter thoroughly and completely before using your CS-2 module. Location The processor module must be located in a CS-2 Bay. This provides a firm level support for the module and has been designed to maximise the flow of cooling air through the module. -
Page 18: Using The Meiko Beta Phase Controller
The bay may carry a number of Beta Phase connections to the module. These connectors must be opened using the Meiko Beta Phase Controller before the module tray is pushed into position. Warning – Failur e to open the Beta Flex connectors befor e pushing the mod- ule trays into position will damage your equipment. -

Page 28: Installation
Installation The same installation procedure is used to install all three board types. Insert the board so that it fits into the guide rails at the top and bottom of the mod- ule, ensuring that the component side is to the left (viewed facing the module). Gently push the board squarely on the front panel. -

Signal Input/Output Pin number DCDB Adding SCSI Peripherals The MK401 includes two SCSI-2 controllers — both SCSI buses are available via connections on the front panel or via the processor module backplane. Up to 3 additional SCSI buses can be added using standard SBus cards, and these are available via connections on the SBus cards. -
Page 34: External Indicators
If either the front panel connections or the backplane connections are used, or no devices are attached at all, then the on-board termination must be turned on. Only when both front-panel and backplane connectors are used together should the on- board termination switches be turned off, and in this case the SCSI bus must be terminated at both ends. -

Installing Backplane Boards Warning – The procedures in this chapter must only be undertaken by trained engineers. Warning – You must disconnect the power supply befor e installing boards into the processor module. A number of boards can be connected to the rear of the processor module. Along the top edge of the module backplane are connectors for up to 8 switch cards. -
Page 44: Mk511/2 Module Switch Cards
Insert the card into the card guides ensuring that the component side of the card faces the right. Firmly push the card into the position ensuring that the card mates correctly with the backplane connection. After installing a module controller card you must reinstall the blanking plate. MK511/2 Module Switch Cards Up to 8 module switch cards can be connected to the module backplane to pro- vide a first layer of switching. -
