Power supply usage
The Ruckus ICX 7650-48ZP and ICX 7650-48P switches support specific AC power supply inputs and numbers of POE, POE+, High
PoE, and PoH ports.
Using a second power supply
In the event of an AC power loss or power supply failure, a redundant power supply (second power supply) can be installed as a backup
power source to a switch. Each power supply provides a load-sharing and redundant power source (up to 250 W AC for non-PoE
switches, and 1000 W AC for PoE switches).
Ruckus recommends that you pay attention to the PoE, PoE+, High PoE, and PoH port configuration (referred to as PoE in this section) of
the switch when using a redundant power supply. When using a single power supply, a PoE switch has a maximum number of supported
PoE ports. Ruckus recommends that when a redundant power source is used for a PoE switch, that the maximum number of PoE ports
supported by the switch must not exceed that which can be supported by a single power supply.
For example, a Ruckus ICX 7650-48P has two power supplies installed. If you increase the maximum number of PoE ports that can be
supported, and if the primary power supply fails, the redundant power supply cannot guarantee the device is protected by backup power.
The redundant power supply will not have enough power to sustain the failed primary power supply. In this case, the device can go down
even with the redundant power supply connected.

DANGER
Make sure that the power source circuits are properly grounded, then use the power cord supplied with the device to connect
it to the power source.
DANGER
If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.
CAUTION
Disassembling any part of the power supply and fan assembly voids the warranty and regulatory certifications. There are no
user-serviceable parts inside the power supply and fan assembly.
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan
trays are clearly labeled with either a green arrow with an "E", or an orange arrow with an "I."
