Power Supply Overview
The Ruckus ICX 7850 switch supports alternating-current (AC) and direct-current (DC) power supplies. The Ruckus ICX 7850 switch is
capable of running on one power supply and four fan assemblies. The second power supply and fifth or sixth fan assembly provide
redundancy.
If the power supply and fan assembly slots are unused, you must cover them with filler panels.
NOTE
Ruckus recommends that the Ruckus ICX 7850 switch operate with two power supplies and five fan assemblies installed. If a
power supply or fan assembly fails, it must be replaced as soon as possible.
NOTE
AC and DC power supplies can be installed and used in the same device.
The power supplies in the Ruckus ICX 7850 switch chassis can be removed and replaced without special tools. The device can continue
operating during the replacement.
The device supports the following types of power supplies:
•
AC power supply with nonport-side air exhaust. This unit moves the air from the port side to the nonport side of the device.
•
AC power supply with nonport-side air intake. This unit moves the air from the nonport side to the port side of the device.
•
DC power supply with nonport-side air exhaust. This unit moves the air from the port side to the nonport side of the device.
•
DC power supply with nonport-side air intake. This unit moves the air from the nonport side to the port side of the device.
