Airespace Wireless Switch Direct Connect Mode
Direct Connect Mode
The 4012 and 4024 Airespace Wireless Switches can be operated in Direct Connect Mode, in Appliance
Mode , or in Hybrid Mode . In Direct Connect Mode, the Airespace Wireless Switches are directly
connected to up to 24 (Model 4024) or up to 12 (Model 4012) Airespace APs and/or third-party APs
over CAT-5 or higher Ethernet cabling. The benefit of this mode is that the Airespace Wireless Switches
can provide
Power Over Ethernet .
The following figure shows an Airespace Wireless Switch in the Direct Connect Mode, and the rest of the
section describes the 4012 and 4024 Airespace Wireless Switch connections to the switched network.

Airespace Wireless Switch Direct Connect Mode
The Airespace Wireless Switch filters packets and forwards them between LAN segments. When the
Airespace Wireless Switch is operated in Direct Connect Mode, it transmits data between all connected
Airespace APs and third-party APs, which results in fewer packets being placed on the backbone
network.
The 4012 and 4024 Airespace Wireless Switches communicate with the backbone network via a
1000Base-T or 1000Base-SX Network Port, or via front-panel 10/100Base-T Ethernet Port 1 as
described in the
Switched Network Connection to an Airespace Switch or Appliance section.
Note:
When you use front-panel 10/100Base-T Ethernet Port 1 to communicate with the
switched network, you can no longer use that port to communicate with an Airespace AP or
third-party AP.
The Airespace Wireless Switch or WLAN Appliance uses industry-standard SNMP traps and flags to
communicate with the
Airespace Control System Software , and communicates with AireOS manage-
ment interfaces as follows:
•
With an optional ACS Software Server or other AireOS management interface, either directly
connected or through an out-of-band AireOS Management Network, or via a dedicated 10/
100Base-T
Service (Management) Port .
•
With an optional VT-100 CLI console via a serial RS232-C Console Port.
Note:
Airespace recommends that you not use the switched network for your AireOS manage-
ment, because a service outage on your switched network means that you have no dedicated
path to the Airespace Wireless Switch.
The Airespace Wireless Switch can be equipped with built-in Power Over Ethernet circuitry or an
external PoE hub, which allows associated Airespace APs and/or third-party APs to receive power over
the CAT-5 Ethernet cabling.
