On Adaptec Series Q controllers, the daughterboard is pre-installed onthe controller. On Adaptec RAID controllers with optional zero maintenance cache protection (seeAdding a Flash Backup Module on page 16), the daughterboard is user installed. The supercapacitormodule is always user installed.The following instructions describe how to install the supercapacitor module using the mounting platemethod. Refer to the flyer in the flash module distribution kit for details about installing thedaughterboard on the RAID controller, as needed, and for other supercapacitor installation options.Warning: Do NOT remove or insert a fully charged supercapacitor module. Always discharge the unitfirst to avoid damage to the controller or flash backup module. The factory ships with discharged units,so they are safe to install when you receive them. To ensure that an installed unit is discharged, switchyour system OFF, then wait 5 minutes. After a dirty shutdown, wait 3 minutes after backup is complete,then remove the unit.To install an Adaptec RAID controller with zero maintenance cache protection:1. Assemble the mounting plate and attach the supercapacitor module:a) Attach the full-height bracket to the mounting plate. The full-height bracket is installed on thefront side of the mounting plate (the side with the bents), with the mounting screws insertedfrom the back, as shown below. Be sure to attach the mounting plate to the bracket with recessedside at the bottom!28Proprietary and Confidential to PMC-Sierra, Inc.Document No.: CDP-00277-01-A Rev.
