Dell PowerConnect W-AirWave includes the 64-bit CentOS operating system based on Red Hat Enterprise
Linux (RHEL) and is installed by default.
NOTE: If you choose to install RHEL instead of the supplied CentOS, you will need to purchase your own RHEL license and support
separately.
Your hardware should incorporate margin for WLAN expansion as well as future AirWave features and modules.
These recommended specifications are formulated to keep AirWave running on the same hardware platform for
up to three years.
Factors which influence the processing requirements for your AirWave server:
How many devices will the server manage?

How often will AMP communicate with these devices?

CAUTION: To ensure hardware capability, purchase server hardware that is certified to be compatible with Red Hat Enterprise
Linux 5 (RHEL5).
