3.5.7 Connecting a Power Cable
The following describes how to connect AC and DC power cables. Connect AC or
DC power cables based on the PSU type.
Before connecting power cables, ensure that the server and its internal
components have been installed, and the PGND cable is connected to the server
(for the RH2288H V3, which does not provide ground terminals, connect the
PGND cable to the cabinet where the server is located). Use dedicated power
cables to ensure equipment and personal safety. Power cables must be securely
connected. Power cables are used only for dedicated servers. Do not use them for
other devices.
The following tools are available:
ESD wrist strap or ESD gloves: used to prevent ESD damage
Connecting an AC Power Cable
Step 1 Wear an ESD wrist strap.
Step 2 Connect one end of the AC power cable to the power port on the PSU of the
server.
● If the PSU has a velcro strap, use the velcro strap to bind the power cable to
the middle of the PSU handle after connecting the power cable to the PSU to
prevent power cable poor contact or disconnection. See Figure 3-24.
