Chapter 2 Installation Instructions The special design of the SC742 chassis allows it to either be used as a tower or as a rackmount system. There are several versions of the chassis, which differ primarily in the power supply and IDE/SCSI configuration. Please refer to the following instructions when working on the SC742. I. Removing the Chassis Side Cover: You will need to remove the chassis side cover to: A. Remove or install drives into any of the 5 ¼” drive bays. B. Replace chassis fans. C.
A. Removing/Installing Drives into the 5 ¼” Drive Bays: Procedure: 1. With the side chassis cover removed, you have access to the 5 ¼” drive bays. 2. Remove the screws to the bay you wish to install or remove a component from. The chassis comes with dummy modules in all the bays to maintain proper airflow – these should remain in the chassis until you add a component. Note that the top two bays are combined into a single module.
B. Removing/Installing Chassis Fans into the 5 ¼” Drive Bays: Procedure: 1. To remove the hot-swap chassis fans, grasp the fan handle while squeezing the locking tab. Pull the fan unit up and out of the chassis. Reverse this procedure to install a fan (replace with the exact same type of fan). 2. If installing an extended ATX motherboard, you may need to remove the fan mounting bracket the fans are attached to for better access. To do so, first remove both fans by following step one.
II. Removing the Front Chassis Cover: You do not need to remove the front bezel to access the drives: Procedure 1. Push on the three tabs on the inside left side lip of the front chassis cover. Push the same side of the cover out about ½ inch. Push on the open side of the cover to remove it from the chassis (do not try to swing or pull it straight out after opening the left side). 2 1 Front Cover Push the tabs toward the lip and (1) push that side of the cover out from the chassis.
III. Removing the Top Chassis Cover and Chassis Feet to Install as Rackmount: You will need to remove the top chassis cover to add rack rails to the chassis: Note: Rail assemblies are optional. P/N: CSE-PT26B (black) and CSE-PT26. Procedure 1. Push the release tab in the center of the cover lip while pushing the cover toward the rear of the chassis at the same time. After the cover stops, lift it off. 2. Each chassis foot has a single screw.
