Preparation Procedures - HPE ProLiant DL320 Gen11 Maintenance And Service Manual

CAUTION: CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating UPS. This device protects the
hardware from damage caused by power surges and voltage spikes and keeps the server in operation during a power
failure.
CAUTION: CAUTION:
To prevent damage to electrical components, properly ground the server before beginning any installation, removal, or
replacement procedure. Improper grounding can cause electrostatic discharge.
CAUTION: CAUTION:
To avoid data loss, Hewlett Packard Enterprise recommends that you back up all server data before installing or removing
a hardware option, or performing a server maintenance or troubleshooting procedure.
CAUTION: CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this
manner results in improper airflow and improper cooling that can lead to thermal damage.
