[. . . ] DO NOT attempt the procedures in the following sections unless you are confident of your capability to perform them. Otherwise, ask a service technician for assistance. 3-10 AcerAltos 19000Pro4 System Guide 3. 1. 4 Installing External Devices The housing supports one 3. 5-inch and three 5. 25-inch external devices. The empty drive bays on the upper front panel allow you install additional external devices such as a CD-ROM drive, digital audio tape (DAT) drive or another hard disk drive. Your basic system comes with a CD-ROM drive and a 3. 5-inch diskette drive already installed. Follow these steps to install an external device: 1. Remove the upper front panel door and the front panel cover. See Figures 3-5 and 3-6 for illustrations. Attach the drive guides on the sides of the external device that you wish to install. Figure 3-11 Attaching the Drive Guides If you are installing a SCSI device, set its SCSI ID. Set the terminator if the SCSI device is the last one on a SCSI bus. System Configuration 3-11 3. Insert the drive into the bay. Figure 3-12 4. Installing an External Device Connect the drive power and signal cables. 3-12 AcerAltos 19000Pro4 System Guide 3. 1. 5 Installing a Hot-swappable SCSI Drive The system supports three kinds of hot-swappable drive trays, one with wide SCSI interface board and one with narrow SCSI interface board. The third is the single connector architecture (SCA) type. The installation steps for the wide and narrow SCSI drives are basically the same except for connecting the wide SCSI drive ID cable. Refer to section 3. 1. 2 for instructions on opening the door. Remove all the screws (about nine screws) that secure the air guide to the housing. Carefully take out the air guide from the housing and set it aside. See Figure 3-21 on the next page for an illustration of the above procedure. System Configuration 3-19 Figure 3-21 Removing the Thermal Air Guide 3-20 AcerAltos 19000Pro4 System Guide Reinstalling the Thermal Air Guide Follow these steps to replace the thermal air guide back into the housing: 1. Position the air guide on its place between the hard disk drives and the power supply rack. Make sure that the air guide fits properly in place. Close and lock the right panel door. The following figure illustrates the above procedure.
