not authorized by Dell is not covered by your warranty. Read and follow all safety instructions that came with the
product.
CAUTION:
Wire the unit with copper only, unless otherwise specified, use only 10 American Wire Gauge (AWG) wire
rated minimum 90ºC for source and return. Protect the –(48–60) V DC (1 wire) with a branch circuit over-current
protection rated 50 A for DC with a high interrupt current rating.
CAUTION:
Connect the equipment to a –(48–60) V DC supply source that is electrically isolated from the AC source
(reliably grounded –(48–60) V DC SELV source). Ensure that the –(48–60) V DC source is efficiently secured to earth
(ground).
NOTE:
A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field
wiring.
Input requirements
•
Supply voltage: –(48–60) V DC

Required wires
•
One UL 10 AWG, 2 m maximum (stranded) black wire [–(48–60) V DC].

System board
Removing the system board
Prerequisites
CAUTION:
If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create
a recovery key during program or System Setup. Be sure to create and safely store this recovery key. If you replace this
system board, you must supply the recovery key when you restart your system or program before you can access the
encrypted data on your drives.
CAUTION:
Do not attempt to remove the TPM plug-in module from the system board. Once the TPM plug-in module is
installed, it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in
module breaks the cryptographic binding, and it cannot be re-installed or installed on another system board.
1. Follow the safety guidelines listed in
2. Follow the procedure listed in
3. Remove the following:
CAUTION:
Do not lift the system board by holding a memory module, processor, or other components.
a.
Air shroud
b.
All expansion cards and risers
