• When mixing drive backplane configurations, you must install all 1.8-inch solid state drive backplanes
above all 2.5-inch hard disk drive or 2.5-inch solid state drive backplanes. See “Drive IDs” on page 67 for
drive ID assignment information and “Supported drive backplane configurations” on page 69 for
information about the combination of supported drive backplane configurations.
• The electromagnetic interference (EMI) integrity and cooling of the server are protected by having all bays
and PCIe slots covered or occupied.
Note:
When you install a drive, save the EMC shield and filler panel from the bay in the event that you
later remove the device.
Drive IDs
This topic provides information about the drive IDs associated with the drive bays.
The hot-swap-drive ID that is assigned to each drive is printed on the front of the server. The following
illustrations show the locations of the IDs of the drives. The ID numbers and the drive bay numbers are the
same.
Notes:
1. When you mix drive backplane configurations, IMM renumbers the drive bay IDs automatically.
2. When mixing drive backplane configurations, you must install all 1.8-inch solid-state drive backplanes
above all 2.5-inch hard disk drive or 2.5-inch solid-state drive backplanes.
3. If you install a 8x1.8-inch drive backplane assembly, the drive IDs that are indicated on the server front
bezel will no longer be valid. Use the drive labels that come with the backplane to renumber the drive IDs
on the bezel.
4. See the following examples and the illustrations in “Supported drive backplane configurations” on page
69 for more information.
The following illustration shows an example of the drive bay IDs in sequential order with a 1.8-inch drive
backplane and a 2.5-inch drive backplane installed.
3 2.5-inch HDD/SSD drive
2 2.5-inch HDD/SSD drive
1 2.5-inch HDD/SSD drive
0 2.5-inch HDD/SSD drive
