80 Hardware Maintenance Manual: xSeries 250
Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate the system while a hard disk drive is removed or installed. These drives are
known as hot-swap drives.
Each hot-swap drive has two indicator lights on the front of the server. If the amber
hard-disk status light for a drive is lit continuously, that individual drive is faulty and
needs to be replaced. When the hard-disk status light indicates a drive fault, you can
replace a hot-swap drive without turning off the server.
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a single connector attachment (SCA) connector. Hot-swap-
drive trays come with hot-swap drives.
Internal drive bays
Internal drives are installed in bays.
Your server comes with one CD-ROM drive and one 3.5-inch, 1.44 MB diskette
drive.
The left front bays support 5.25-inch, half-high, removable-media drives. Any
two adjacent 5.25-inch, half-high bays can be converted to a single full-high bay.
Note: The server EMI integrity and cooling are both protected by having the left
front bays covered or occupied. When you install a drive, save the filler
panel from the bay, in case you later remove the drive and do not replace it
with another.
You cannot install hard disk drives in the left front bays. You can install hot-swap
hard disk drives only in the hot-swap hard disk drive bays on the right front side
of the server.
If you are installing a device with a 50-pin connector in one of the left front bays,
you will need a 68-to-50-pin converter (option number 32G3925).
Your server supports ten 1-inch (26 mm) slim-high, 3.5-inch hot-swap hard disk
drives in the hot-swap bays.
