Installing a hot-swap SAS or hot-swap SATA hard disk drive
Some hot-swap SAS models support 2.5-inch or 3.5-inch hot-swap SAS hard disk
drives. The hot-swap SATA models support 3.5-inch hot-swap SATA hard disk
drives. Before you install a hot-swap hard disk drive, read the following
information:
v Depending on your model, the server supports the following maximum number
of hot-swap drives:
– Four 3.5-inch hot-swap SAS (seven-drive-bay model)
– Four 3.5-inch hot-swap SATA (seven-drive-bay model)
– Four 2.5-inch hot-swap SAS (seven-drive-bay model)
– Eight 2.5-inch hot-swap SAS (eleven drive-bay model)
v You must install either all SAS hard disk drives or all SATA hard disk drives in
the server. Do not install both SAS and SATA drives in the server.
v Install drives in the following sequence:
– For server models that support four hot-swap hard disk drives, install the
drives starting from the top bay to the bottom bay (bay 4, 5, 6, and then 7).
– For server models that support eight hot-swap hard disk drives, install the
drives starting from left to right (bay 4, 5, 6, 7, 8, 9, 10, and then 11).
v Inspect the drive tray for signs of damage.
v Make sure that the drive is correctly installed in the tray.
v You do not have to turn off the server to install hot-swap drives in the hot-swap
drive bays.
The server hot-swap bays are connected to a SAS/SATA backplane. This
backplane, also known as the hot-swap-drive backplane, is the printed circuit
board behind these bays.
Attention: Static electricity that is released to internal server components when
the server is powered-on might cause the server to stop, which might result in the
loss of data. To avoid this potential problem, always use an electrostatic-discharge
wrist strap or other grounding system when you work inside the server with the
power on.
To install a hot-swap hard disk drive, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 19.
2. Unlock the side cover (the bezel will not disengage from the server if the cover
is locked).
3. Remove the lower bezel (see “Removing the two-piece bezel” on page 24).
4. Touch the static-protective package that contains the drive to any unpainted
metal surface on the server; then, remove the drive from the package and place
it on a static-protective surface.
5. Install the hard disk drive in the hot-swap bay:
a. Make sure that the drive tray handle is open.
b. Align the drive assembly with the guide rails in the bay as shown in the
following illustrations based on your model.
