Power supply overview
The ExtremeRouting SLX 9640 device supports alternating-current (AC) and direct-current (DC) power
supplies. The SLX 9640 device is capable of running on one power supply and five fan assemblies. The
second power supply and sixth fan assembly provide redundancy.
If the second power supply and sixth fan assembly slots are unused, you must cover them with filler
panels.
Note
Extreme Networks recommends that the SLX 9640 device operate with two power supplies
and six 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 SLX 9640 device 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.
