Installing Power Supplies and Disk Drives

This section provides information about installing hot swap power supplies and hot plug disk drives. Hot swap power supplies and hot plug disk drives are located behind the front bezel.




	CAUTION: A hot plug device may require interaction with the operating system before the device can be safely installed into the server. Verify that the operating system supports installing disk drives while the operating system is running. If the operating system does not support this feature, shut down the operating system before attempting this procedure. Failure to observe this caution will result in system failure.




	NOTE: A hot swap device does not require interaction with the operating system before the device is removed from or installed into the server. The AC power to the server does not have to be off to install a hot swap power supply.

Opening the Front Bezel

The front bezel is hinged on the left (facing the front of the server). The server does not have to be turned off to open or to completely remove the front bezel.

Opening the front bezel provides access to the following components:

Hot plug disks (up to four)
Removable media (DVD ROM drive, etc.)
Hot swap chassis fan cover
Hot swap chassis fans (front and rear)
Hot swap power supplies (up to three)

To open the front bezel, perform the following step:

Grasp the handle located at the right edge of the front bezel and pull out. The front bezel will swing away from the chassis.

Installing Hot Swap Power Supplies

Power Supply Load Order

There is no specific load order requirement for hot swap power supplies. However, the supported configuration of an hp Integrity rx5670 requires a minimum of two supplies be installed. A third, optional hot swap power supply may be installed to provide N+1 capability.

The right side hot swap power supply is identified as P0, the center hot swap power supply is identified as P1, and the left hot swap power supply is identified as P2. Each hot swap power supply requires a separate power cord be installed in the appropriate power cord receptacle located at the rear of the chassis.

Installing a Hot Swap Power Supply

To install a hot swap power supply, perform the following steps:




	WARNING! Be careful when installing a hot swap power supply. It is heavier than it appears.




	CAUTION: Install the hot swap power supply before attaching the new power cord at the rear of the system if the system is powered down. Failure to observe this caution will result in damage to the server.

Grasp the handle in one hand and support the hot swap power supply with the other.
Slide the hot swap power supply into the server. If the server is powered on, the hot swap power supply LED should illuminate immediately.
Tighten the captive T-15 screw located to the right of the handle near the top of the hot swap power supply.

Installing Hot Plug Disk Drives

Hot Plug Disk Drive Load Order

The disks drives, known as hot plug disk drives, must be installed in a specific order. The hot plug disk drives are located in the disk media housing, found at the front of the chassis. Within the disk media housing are slots that accommodate up to four hot plug disk drives. Hot plug disk drive installation order is shown in Table 2-1 “Hot Plug Disk Drive Load Order”.

Table 2-1 Hot Plug Disk Drive Load Order

Disk	Slot
First disk (A)	Lower left
Second disk (B)	Lower right
Third disk (C)	Upper left
Fourth disk (D)	Upper right

Installing a Hot Plug Disk Drive

To install a hot plug disk drive, perform the following steps:

Ensure that the hot plug disk drive latch is in the open/unlocked position.
Gently slide the hot plug disk drive into the chassis until it locks into place.
NOTE: When the disk drive is properly seated, the notch located at the top of the latch will lock onto the lip located at the top of the disk drive slot in the disk media housing.
