WARNING: A risk of electric shock from high leakage current exists. Before connecting the AC supply to the power enclosures, be sure that the electrical outlets are properly grounded (earthed). CAUTION: Always be sure that equipment is properly grounded and that you follow proper grounding procedures before beginning any installation procedure. Improper grounding can result in ESD damage to electronic components. For more information, see "Preventing electrostatic discharge (on page 23)." CAUTION: When performing non-hot-plug operations, you must power down the server blade and/or the system. Use caution when performing other operations, such as hot-plug installations or troubleshooting. CAUTION: Protect the equipment from AC power fluctuations and temporary interruptions with a regulating facility UPS device. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the system in operation during a power failure. Power down Be sure that the partner servers are the first units to be powered down and the last to be powered back up. Taking this precaution ensures that the system and the OS are shut down in an orderly manner. IMPORTANT: If installing a hot-plug device, it is not necessary to power down the MDS600. To power down the MDS600: 1. Power down the partner servers. See the server documentation. 2. Press and hold the Power On/Standby button for approximately 4 seconds. This action powers down both hard drive drawers. Extend the hard drive drawer 1. Be sure all I/O bays contain either an I/O module or an I/O blank. The hard drive drawer does not open if I/O bays are empty. 2. Be sure the I/O modules or I/O blanks are fully seated and their handles are in the locked position. The hard drive drawer does not open if I/O modules or I/O blanks are not fully seated with their handles in the locked position. WARNING: TIP HAZARD! To reduce the risk of personal injury or damage to the equipment, do not extend the hard drive drawers beyond the supporting surface when the unit is not installed in a rack. WARNING: To reduce the risk of personal injury or damage to the equipment, ensure that only one hard drive drawer is extended at a time. WARNING: To reduce the risk of personal injury or damage to the equipment, you must adequately support the chassis during installation and removal. It is not secured to the rack frame or mounted on rails. Removal and replacement procedures 25

supply to the power enclosures, be sure that the electrical outlets are properly grounded (earthed).
CAUTION:
Always be sure that equipment is properly grounded and that you follow proper
grounding procedures before beginning any installation procedure. Improper grounding can
result in ESD damage to electronic components. For more information, see "Preventing
electrostatic discharge (on page

)."
CAUTION:
When performing non-hot-plug operations, you must power down the server blade
and/or the system. Use caution when performing other operations, such as hot-plug installations
or troubleshooting.
CAUTION:
Protect the equipment from AC power fluctuations and temporary interruptions with a
regulating facility UPS device. This device protects the hardware from damage caused by power
surges and voltage spikes and keeps the system in operation during a power failure.
Power down
Be sure that the partner servers are the first units to be powered down and the last to be powered back up.
Taking this precaution ensures that the system and the OS are shut down in an orderly manner.

If installing a hot-plug device, it is not necessary to power down the MDS600.
To power down the MDS600:
1.
Power down the partner servers. See the server documentation.
2.
Press and hold the Power On/Standby button for approximately 4 seconds. This action powers down
both hard drive drawers.
Extend the hard drive drawer
1.
Be sure all I/O bays contain either an I/O module or an I/O blank. The hard drive drawer does not
open if I/O bays are empty.
2.
Be sure the I/O modules or I/O blanks are fully seated and their handles are in the locked position. The
hard drive drawer does not open if I/O modules or I/O blanks are not fully seated with their handles
in the locked position.
WARNING:
TIP HAZARD! To reduce the risk of personal injury or damage to the equipment, do
not extend the hard drive drawers beyond the supporting surface when the unit is not installed in
