Connecting Required Cables
Install cables in accordance with all applicable local and national regulations and practices.
Ethernet Ports
The RJ45 Ethernet ports (ENET0 and ENET1) support 100/1000Base-T auto-sensing MDI/MDX
connections. Use these ports to connect the AP to a twisted pair Ethernet LAN segment or directly to an
Aruba Mobility Controller. Use a 4- or 8-conductor, Category 5 UTP cable up to 100 m (325 feet) long.
The 100/1000 Mbps Ethernet ports are on the bottom of the AP. These ports have RJ-45 female
connectors with the pin-outs shown in
Table 1
.
Serial Console Port
The serial console port allows you to connect the AP to a serial terminal or a laptop for direct local
management. This port is an RJ-45 female connector with the pinouts described in
Table 2
. Connect this
port in one of the following ways:
z
Connect it directly to a terminal or terminal server using an Ethernet cable.
z
Use a modular adapter to convert the RJ-45 (female) connector on the AP to a DB-9 (male)
connector, and connect the adapter to a laptop using an RS-232 cable. See
Figure 7
for connector
details of the adapter.
N O T E
Aruba 12x APs are intended only for installation in Environment A as defined in IEEE 802.3.af, Power
