The following table describes the regulatory DC power specifications for the VSP 7200 Series
switch. Note that regulatory power specifications are based on the maximum rated capacity of the
power supplies and are not based on typical power consumption, which is typically lower.
Table 12: DC power specifications
VSP 7254XSQ or VSP 7254XTQ
Input Current:
24–16 A
Input Voltage (rms):
40.5 to 60 VDC
Power Consumption:
800 W maximum
Temperature:
Operating range: 0 to 50 ºC
Non-operating range: -40 to 70 ºC
Inrush Current:
50 A maximum
Turn on Condition:
500 ms maximum after application of DC power
Important:
12 V output rise time, from 10 to 90 percent, must be the maximum of 70 ms and monotonic under all
defined input and output conditions.
Efficiency:
• 88% minimum at 100% load level
• 92% minimum at 50% load level
• 88% minimum at 20% load level
• 80% minimum at 10% load level
Removing a power supply
You can hot swap power supplies while the switch is operational.
Procedure
1. Disconnect the power cord from the power supply.
2. Lift up the power supply handle so you can grasp it.
3. Push the spring latch to the left and use the power supply handle to pull the power supply
out of the chassis.
4. If you are replacing the power supply, see
on page 24 or
on page 29. If not, re-install the filler panel.
