Chapter 4 Installation and Maintenance
Removing and Replacing a Power Supply Unit
Note
Simple Network Management Protocol (SNMP) monitors the activity of the power supplies. In most
cases when a power supply problem occurs, an SNMP trap is sent in SNMP and the appropriate message
is posted on the SCE 2000 CLI.
Power Supply Specifications
lists the AC-input and DC-input power supply specifications for the SCE 2000 platform.
Note
For AC-input power, we recommend powering the SCE 2000 platform from a 120 VAC, 15A receptacle
U.S. (240 VAC, 10A international) at the power source.
Powering Down the Power Supply Unit and Disconnecting Input Power
The following sections describe how to remove power from an AC-input power supply and a DC-input
power supply:
