HP StorageWorks Modular Smart Array 50 Storage Enclosure Maintenance and Service Guide • Place parts on a grounded surface before removing them from their containers. • Avoid touching pins, leads, or circuitry. • Always be properly grounded when touching a static-sensitive component or assembly. Rack warnings WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that: • The leveling jacks are extended to the floor.
Removal and replacement procedures IMPORTANT: If installing a hot-plug device, it is not necessary to power down the storage enclosure. 1. Power down any attached servers. Refer to the server documentation. 2. Press the Power On/Standby button on the storage enclosure. Wait for the system power LED to go from green to amber. 3. Disconnect the power cords. The system is now without power.
HP StorageWorks Modular Smart Array 50 Storage Enclosure Maintenance and Service Guide Hard drive blank CAUTION: To prevent improper cooling and thermal damage, do not operate the storage enclosure unless all bays are populated with either a component or a blank. To remove the component: To replace the blank, slide the blank into the bay until it locks into place. Hot-plug SAS or SATA hard drive You can replace hard drives without powering down the system.
Removal and replacement procedures 11 To minimize the likelihood of fatal system errors, take these precautions when removing failed drives: • Do not remove a degraded drive if any other drive in the array is offline (the Online LED is off). In this situation, no other drive in the array can be removed without data loss. Exceptions: – When RAID 1+0 is used, drives are mirrored in pairs.
HP StorageWorks Modular Smart Array 50 Storage Enclosure Maintenance and Service Guide 3. Remove the hard drive. To replace the component: 1. Slide the drive into the cage until it clicks, locking the drive into place. 2. Close the lever. IMPORTANT: When the drive is inserted, the drive LEDs flash for 2 seconds to indicate that the drive is seated properly and receiving power. 3.
Removal and replacement procedures To remove the component: 1. Disconnect the power cord from the power supply. 2. Remove the power supply. To replace the component, reverse the removal procedure. Hot-plug fan CAUTION: To prevent improper cooling and thermal damage, do not operate the storage enclosure unless all bays are populated with either a component or a blank.
HP StorageWorks Modular Smart Array 50 Storage Enclosure Maintenance and Service Guide To remove the component: To replace the component, reverse the removal procedure. I/O module CAUTION: To prevent improper cooling and thermal damage, do not operate the storage enclosure unless all bays are populated with either a component or a blank. To remove the component: 1. Power down the storage enclosure (on page 8). 2. Disconnect any SAS cables connected to the I/O module.
Removal and replacement procedures 15 3. Remove the I/O module. To replace the component, reverse the removal procedure. Midplane and backplane To remove the components: 1. Power down the storage enclosure (on page 8). 2. Remove the fan assembly ("Hot-plug fan" on page 13). 3. Remove all hot-plug power supplies ("Hot-plug power supply" on page 12). 4. Remove the I/O module ("I/O module" on page 14). 5. Remove all hard drives ("Hot-plug SAS or SATA hard drive" on page 10). 6.
