2.6.4.2 Rear View of the ProCurve 2848 Switch
The HP ProCurve 2848 switch has a power connector, but it does not have a power switch. It is
powered on when connected to an active AC power source. The switch automatically adjusts to
any voltage between 100 volts and 240 volts (50–60 Hz). No voltage range settings are required.
When the switch is powered on, it performs a diagnostic self-test that takes about 50 seconds to
complete.
The console port on the back of the ProCurve 2848 switch ( Figure 2-14 “HP ProCurve Switch
2848 Rear View” ) connects the switch to a console via a serial cable. The console can be a PC or
a workstation running a VT-100 terminal emulator. The RPS slot allows you to connect the
ProCurve 2848 to a redundant power supply unit (optional).
