Internal Power Supply External RPS
X440-G2-12p-10GE4 200 W 200 W - Redundant power only
X440-G2-24p-10GE4 380 W 380 W - Redundant power only

External Redundant Power Supplies for Non-PoE Switches
All X440-G2 series non-PoE switches ship with one fixed internal power supply. If redundancy is
required, an external RPS can be attached to the switch.
5
Minimum is defined as idle, with no ports linked. Maximum is defined as fans high, all ports 100% trac.
6
The power supplies will continue to operate at +/- 10% of the rated input to accommodate temporary loss of input
voltage regulation.
7
The extended temperature switches are the X440-G2-24fx-GE4, X440-G2-12p-10GE4, and X440-G2-24t-GE4.
