Setting Aruba 2E Parameters
1. From the apboot prompt, configure the host information, if necessary.
In order to provide centralized management of the APs, each Aruba AP
downloads its software image and configuration files from a master Mobility
Controller.
Setting the correct host information depends on the following:
Does your network use direct IP addresses or DNS with host names?
If using host names, is aruba-master acceptable for the master Mobility
Controller, or do you need to define a different name?
Depending on your answers, select one of the following steps:
zMy network uses DNS and the aruba-master host name is acceptable.
This is the default. It requires your DNS to be configured to resolve
“aruba-master” to the IP address of the master Mobility Controller. Unless
your system has been previously configured for different settings, you
can skip to Step 2.
Otherwise, if your system was previously configured for a different
setup, manually set the servername environment variable to the default
host name:
NOTE:The master and serverip environment variables also affect how AP
source files are selected and should be cleared when using this
approach. To clear a variable, enter the setenv variable command with
no host name or address value:
apboot> setenv master
apboot> setenv serverip
When finished, proceed to Step 2.
zMy network uses DNS, but I will use a different host name for the
Mobility Controller.
This requires that the servername variable be configured with your chosen
host name for the master Mobility Controller. It also requires that your
DNS be configured to resolve the specified host name to the IP address
of the master Mobility Controller.
To manually set the host name, use the following command:
apboot> setenv servername aruba-master
apboot> setenv servername
<Mobility Controller host name>

NOTE:The master and serverip environment variables also affect how
source files are selected and should be cleared when using this
approach. To clear a variable, enter the setenv variable command with
no host or address value.
When finished, proceed to Step 2.
zMy network uses direct IP addresses instead of DNS.
If using direct IP addresses in your network, use the following
commands:
NOTE:If the servername variable is configured in this scenario, it will be
ignored.
2. Specify an IP address for a specific AP, if necessary.
If using DHCP, the AP will obtain its IP address automatically and you can
skip this step. Otherwise, configure the AP with a static IP address using the
following commands:
apboot> setenv serverip <Mobility Controller IP address>
apboot> setenv master <Mobility Controller IP address>
apboot> setenv ipaddr <static IP address for the AP>
apboot> setenv netmask <static IP address mask>

Installation Guide September 2006
Selecting an FE Cable
The 10/100 Mbps Ethernet (FE) port is used to connect the AP to a
10Base-T/100Base-TX (twisted-pair) Ethernet LAN segment. The appropriate FE
cable depends on the features required of the FE port:
SPOE
When connecting the AP to a device that supports Serial and Power Over
Ethernet (SPOE), use an 8-conductor, Category 5 UTP, straight-through FE
cable.
The Aruba 5000 (with Line Card LC-5000-24FE-2GE-SPOE), the Aruba 2400,
and the Aruba 800 support SPOE.
POE
If the connecting device supports only Power Over Ethernet (POE), use a 4- or
8-conductor, Category 5 UTP, straight-through FE cable.
Network Only
If the connecting device does not support POE, use a 4- or 8-conductor,
Category 5 UTP, FE cable. The port detects MDI/MDX and automatically
adjusts for straight-through or crossover cables.
The maximum length for FE cables is 100 meters (325 feet).
When the Aruba 2E is installed in an air-handling space, such as above
suspended ceilings, as described in National Electrical Code (2002) Article
300.22(C), and Canadian Electrical Code, Sections 2-128, 12-010(3) and 12-100,
Part 1, CSA C22.1, POE is required. Also, any FE cable installed in such spaces
should be suitable under NEC Article 800.50 and marked accordingly for use in
plenums and air-handling spaces with regard to smoke propagation, such as
CL2-P, CL3-P, MPP, or CMP.
Install cables in accordance with all applicable local and national regulations and
practices.
For more port and cable details, see Appendix A, “Port Specifications”.
Connecting Cables and Power
CAUTION:To prevent personal injury or damage to equipment, be
sure to comply with electrical grounding standards during
all phases of installation and operation of the AP. Do not
allow the Aruba 2E or its attachments to be connected to
