Power Connectors
The switch does not have a power switch; it is powered on when it is connected
to either an active AC power source, using the AC power connector, or an
active HP RPS, using the RPS power connector. Using the AC power
connector, the switch automatically adjusts to any voltage between 100-127
and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings
required.
Redundant Power Supply (RPS) Connector
The RPS connector allows you to connect this switch to the HP J2962A
Redundant Power Supply. A single RPS shares the load with up to 4 switches.
The RPS has redundant power supplies to keep the switch up and running; it
is used in place of the switch’s standard power cable (NOT in addition to it).
Expansion Slot
The Expansion Slot is used to add connectivity/functionality through modules
such as the HP J3138A AdvanceStack Internet Router Module to the switch.
Other modules may be available. Contact your HP-authorized dealer or
reseller for more information.
Expansion slot modules have a colored extractor handles that match a color
bar on the switch. Before inserting a module, verify that the color matches.
