Insert the new PSU module into the subsystem Once the previously removed cooling module has been installed, insert the new PSU module into the subsystem. Make sure the extraction lever is in its downright position so that the saddle notches on the lower edges of the handle can lock on to the edge metal brackets along the chassis inner walls. Push the PSU into the slot and pull the handle upwards to secure the module 6.6.2Replacing a Cooling Fan Module Notes on Cooling Fan Module MaintenanceReplacing a Failed Cooling Fan Module 6.6.16.7.2Replacing a Failed Hard Drive Drive Tray MaintenanceNotes on Hard Drive Maintenance 6.7.1Drive type The subsystem can use either SATA-II or SATA-I hard drives Fig. 6.10 Installing a SATA Hard Drive Dimensions Appendix Technical SpecificationsEnvironmental Specifications Power RequirementsVibration Safety RequirementsWarning Alarms Shock7.1.1 Controller SpecificationsConfiguration SpecificationsPower Supply Specifications Drive Tray SpecificationsRAID Management Cooling Module SpecificationsFault Tolerance Management 8.1.1 Appendix Spare Parts and AccessoriesSpare Parts List Spare PartsAccessories and Optional Items Appendix Pinouts SCSI Port VHDCI Connector PinoutsCN2 Pin Number COM1 Cable DB9 and Audio Jack PinoutsCN1 Pin Number Pin NameEthernet Port Pinouts Main PowerNull Modem 10 Index ventilation clearance warning alarmsterminal emulation program 17 terminal management 14 threshold values under chargePage Telefon Bosch Security SystemsRobert-Koch-Straße D-85521 Ottobrunn Germany
