Chapter 4 Installing Mass Storage Devices If there are gaps in the cage, the drives may not receive the proper ventilation and could suffer thermal damage. • Filler Panels and Spacers ◊ Ensure all empty slots in the Hot Swap drive cage have filler panels inserted to ensure proper airflow. If there are fewer drives than the Hot Swap drive cage supports, a 1-inch filler panel must be inserted in each empty disk location. The filler panels ensure the drive cage has the proper ventilation and airflow. The filler panel will be removed before inserting a new drive. ◊ Ensure all smaller spaces in the Hot Swap drive cage have the smaller filler panels inserted to ensure properly airflow. If there is a mix of 1-inch and 1.6-inch drives in the drive cage, you may need to add ½-inch drive spacers. The smaller drive spacer fills the gap between adjacent drives or between a drive and a filler panel. Disk spacers can be mounted on 1-inch low-profile drives or 1.6-inch half-height drives, so a drive spacer and low-profile drive are the same size as a half-height drive, and a drive spacer and a half-height drive are as large as two low-profile drives. CAUTION To prevent overheating or excessive electromagnetic radiation, use the filler panels and spacers to fill the gaps between Hot Swap hard drives. If the filler panels or spacers are left out of the drive shelves, thermal damage and/or excessive EMI could occur. • Hot Swap Drive Cage Configurations The possible Hot Swap Drive Cage Configurations are summarized in Figures 4-2 through 4-5 for the HP NetServer's LC 2000r and LC 2000 respectively. There are various SCSI cable configurations associated with the system and, if incorrectly configured, could cause damage to the HP NetServer and the SCSI devices. Refer to Figures 4-6 and 4-7. Hot Swap Configuration Options The Hot Swap Mass Storage Cage has various configurations which affects the options installed and cable configurations. If the Duplex board is installed on the mass storage cage, the drive and cable configurations differ from those shown without the duplex board installed. Compare Figures 4-2 and 4-4 or 4-3 and 4-5. 38
