Ruckus ICX 7450 Switch Hardware Installation Guide 45
Part Number: 53-1003899-09
Power supplies
The Ruckus ICX 7450 supports alternating-current (AC) and direct-current (DC) power supplies. The Ruckus ICX 7450 is capable of
running on one power supply and one fan. The second power supply and second fan provide redundancy.
If the second power supply and second fan slot are unused, you must cover them with filler panels.
Ruckus recommends that the Ruckus ICX 7450 switch operates with two power supplies and two fan trays installed. If a power
supply or fan tray fails, it must be replaced as soon as possible.
AC and DC power supplies cannot be installed and used in the same device. Mismatched power supplies in the same device
cause continual reboot on power up.
Power supply usage
The Ruckus ICX 7450-24P, ICX 7450-32ZP, and ICX 7450-48P models support specific AC or DC 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 or 510 W DC for
non-PoE switches, and 1000 W AC or 510 W DC 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.
