Table 3: AC power specifications for 4450GSX-PWR+
4450GSX-PWR+
Input Current 16.66 A/8.33 A
Input Voltage (rms) 100 to 240 VAC at 50 to 60 Hz
Power Consumption • Without PoE+
- Typical: 116 W
- Maximum: 164.6 W
• With PoE+
- Typical power utilization depends on the number
of ports using PoE+.
- Maximum: 553.4 W
Thermal Rating 508 BTU/hr maximum
Inrush Current 70 A maximum
Turn on Condition 1 second maximum after application of AC power
Efficiency 70 percent minimum
Important:
12–volt output rise time, from 10 to 90 percent, must be the maximum of 50 ms and monotonic under
all defined input and output conditions.
DC power specifications
The following table describes the DC power supply specifications for the 4850GTS-DC and the
4450GSX-DC models.

VSP 4000 power supply power specification
The VSP 4000 supports two external field-replaceable power supplies. One power supply ships with
the chassis. You can install a secondary power supply to provide redundancy and load sharing, and
to add Power over Ethernet Plus (PoE+) power budget on PWR+ models.
