W-600 Series Controllers
The W-600 SeriesController is designed for compact, cost-effective "all-in-one" networking solutions. The W-
600 Series includes a firewall, wireless LAN controller, Ethernet switch with PoE+, IP router, site-to-site VPN
edge device, file server, and print server.
The W-600 Series is an enterprise-class, wireless LAN controller that connects, controls, and integrates wireless
APs and Air Monitors (AMs) into a wired LAN system. Table 241 lists some of the hardware features by the
numbers.

Connecting with a USB Cellular Modems
USB Cellular Modems are supported via a USB port. ArubaOS supports several EVDO (Evolution Data
Optimized, up to 3.1 Mbps, CDMA) and 3G HSPA (High-Speed Packet Access, 3G data service), and 4G LTE
(Fourth Generation, Long Term Evolution) modems. The 3G HSPA is provided by AT&T in the United States and
numerous other 3G providers worldwide.
How it Works
Plug the USB Cellular Modem into the USB port of the W-600 Series controller. The USB Cellular Modem is
automatically detected and negotiates a PPP IP address. If the modem fails to obtain a PPP IP address within
45 seconds, the controller ignores the modems presence, and boots as if the modem is not present.
Switching Modes
Many of the newer modems contain multiple USB devices; creating a very elegant plug-n-play solution. When
your USB Cellular Modem is first powered on, a storage device is registered. This storage device contains the
software driver/executable necessary to install and operate the modem.
Once the software installation is complete, the modem must mode-switch from a storage device to a registered
modem device. Mode-switching varies by manufacturer. For example, The Novatel modem mode-switches via
a SCSI eject command; the Huawei modem mode-switches via a SCSI rezero command, while the Sierra modem
mode-switches via a specific USB command. Once the mode-switching is complete, the modem automatically
registers itself.
