The ISAP has three sub-miniature version A (SMA) male reverse-polarity antenna connectors for
three external antennas. All three antennas must be connected for correct ISAP operation and
performance. The antennas need to be properly attached.
Warning!
No dust or dirt should get into the connectors.
Info!
It is highly recommended to keep the antennas connected in all situations, as they will
provide needed protection against dust and dirt.
Info!
The ISAP is delivered with mounted antennas. The user would need to replace the
antennas only for maintenance purpose when necessary.
Warning!
Do not apply any forces with any tools to the antenna connectors’ threads when
connecting or disconnection the antennas. The antennas shall be connected and fixed
by hand only.
3.1.3 Reset button
The reset button is a push button, which allows user to reset the ISAP configuration to factory
settings. Resetting the configuration factory parameters is necessary when moving the ISAP to a new
location, or for ITOOLS fault analysis and recovery purposes of ISAP maintenance. Please refer to
chapter 5.6 for details on how to restore the factory settings by using reset button.
Info!
Please reset ISAP only if first level support instructs you to do so. There will be
additional steps to be done by you in order to transfer ISAP configuration from server
ISIS each time you reset ISAP.
3.1.4 LAN connector
ISAP utilizes Ethernet networking topology to connect to the backbone. The connector is RJ45 type
and enables 10/100/1000 Mbit connections. The LAN connector LED will lit green in order to indicate
connection of LAN cable.
3.1.5 USB connector
There is one Type A USB connector located on the ISAP connector panel (see Figure 3-3).
The USB connector is planned to be used for connecting ITOOLS extension to the infrastructure. The
USB connector’s protecting rubber cover should be kept on unless the USB connector is connected
to ITOOLS extension equipment. This prevents dust and dirt to get into the connector.
Warning!
The USB connector shall not be used for anything else than specified ITOOLS
extension devices. Details will be provided by BMW AG as soon as they will be
available.

3.2 Antennas
ISAP includes external WLAN Tri-band small diameter antennas, which cover frequencies from 2.4 to
6 GHz. Omni-directional patterns with gain in upper frequencies give optimal coverage for workshop
environment. The antenna has a gain of 2.1 dBi at 2.45 GHz and 2.5 dBi at 5.875 GHz. The antennas
should be placed so that they are pointing all into different directions. The performance of ISAP is
maximized when antennas create as different (i.e. non-correlating) spatial streams as possible. See
Figure 3-4 below for example how to point antennas.
Figure 3-4: Example of antenna directions
Warning!
Do not push the antennas to the angles which the flexible joint doesn’t easily allow.
Otherwise you might break the joints.

mounting the ISAP to the place where the previous generation Access Point has been mounted
before. For best performance the following notes should be considered and mounting locations
should be selected based on given hints:
1. The mounting location should be selected so that it is central for assumed ITOOLS
operations:
o Mount the ISAP near to the place where wireless networks will be mostly used
o Allow a line of sight contact between the ISAP and the workplace where ITOOLS will
be used
o Installing ISAP high on the wall typically allows best radio coverage and optimum
operation, minimum height of 2 meters is recommended
2. Select the mounting location so that it is free from unnecessary obstacles, or removing
obstacles nearby ISAP installation location
o Obstacles, such as metal surfaces in desks, filing cabinets, bookshelves, and
wastebaskets close to the ISAP may degrade the performance
3. Mounting location distance from the Workshop LAN backbone (ISIS)
o ISAP is connected to ISIS backbone with a 20 meters Ethernet cable
o ISAP mounting point shall be selected so that the supplied 20 meters cable can
connect the ISAP to the ISIS backbone without any cable extension. The Ethernet

5 Registration, Configuration and Operation
5.1 Registration of ISAP
Every ISAP must be registered before the wireless operation is possible. This chapter provides an
overview of ISAP registration.
5.1.1 Automatic registration
Most of the workshops have live connection to BMW AG backend systems. In this normal use case,
the registration of the ISAP is done automatically through Workshop System Management (WSM)
within the first start-up. For further information please refer to the WSM User Guide [1].
5.1.2 Manual registration
In case the workshop does not have a live connection to the workshop database, the registration of
ISAP must be done manually through a registration fax. For further information please refer to the
WSM User Guide [1].
5.2 Configuration and operation
5.2.1 Configuration
The ISAP is configured through Workshop System Management (WSM) software. Please refer to the
WSM User Guide [1] for details on how to configure the ISAP.
5.2.2 Channel scanning
In the workshops there might be no professional site survey available during initial ITOOLS
installation. Therefore the existing other WLAN band activities and users are not necessary known. In
many cases this is not assumed to be a problem, as workshop is normally relatively well controlled
environment. Additional to the disturbances from the workshop there can potentially be other WLAN
Networks from uncontrollable environments close to the workshop, i.e. from other companies. These
devices might be causing disturbances to ITOOLS Wireless Network operation.
Due to these issues it is highly beneficial that ITOOLS operation is adjusted based on the
environment radio operating conditions. Optimally selected radio frequency channel will improve the
ITOOLS operation quality, performance, and service availability.
Channel Scanning introduces a possibility to analyze the installation environment for potential
problems during configuration and also later on- one of causes for problems is the use of shared radio
channels, and the fact that other surrounding networks may change they operation without notifying
for ITOOLS administration. For this reason ISAP is able to provide information about channel
allocation.
Channel Scanning can be activated through Workshop System Management (WSM), in order to get
the channel scan information from ISAP.
Info!
In Workshop System Management (WSM) channel scanning is referred to as the
Channel Wizard. It can be started via the Device Details tab in WSM.
Caution!
Normal operation of the ISAP is deactivated for the channel scan.

Version 1.0/ March 08
The Channel Scan operation is based on reporting all Radio Frequency (RF) signal strength values for
the least used channels, taking into account the other surrounding networks. As a result channel scan
will deliver one recommended channel in 2.4 GHz band as well as one recommended channel in the 5
GHz band. It will also deliver some least used channels for each of the two bands. For more details on
using channel scanning please refer to the WSM User Guide [1].

6 Maintenance
6.1 Status information
The status information of the ISAP can be seen in the Workshop System Management (WSM)
graphical user interface. More information about the queries of the ISAP status is available in the
WSM User Guide [1].
6.2 Cleaning ISAP
The ISAP is not designed to be in direct contact with dust, dirt or other generally harmful substances.
The media found in workshops, such as oils, acids and cleaners are especially dangerous when
applied directly to the ISAP. In addition, the vapors of such substances are harmful, an adequate air
circulation is recommended. Due to these restrictions, it is highly recommended that the ISAP and
the nearby environment of the ISAP are kept clean of substances mentioned above.
Use only a moist cloth to clean the device. Do not use petroleum based substances or solvents as this
may cause corrosion of the surface of the ISAP.
6.3 Cable state
There are two cables delivered with the ISAP: the LAN cable and the power cable. It is recommended
that the user periodically check the condition of these cables. A simple visual check is adequate. The
cable shall not have any visible cut or scratches. If any damage is visible, the broken cable must be
replaced with a new one.
Danger!
Be careful when checking the power cable. The cable must be disconnected from the
power outlet prior to the checking to avoid the risk of an electric shock.
6.4 Replacing a defective cable
Replacement parts can be ordered through the first level helpdesk. Disconnect the ISAP from power
outlet before replacing a defective cable.
6.5 Replacing antennas
The antennas might be replaced for maintenance purposes. The replacement of the antennas might
be ordered through first level helpdesk. To replace an antenna, proceed with the following steps:
1. Unplug the ISAP power cable
2. Unscrew the antenna(s)
3. Attach the new antenna(s) by hand
Warning!
Do not use any tools when attaching or detaching antennas. Applying an excessively
high momentum force may destroy the connectors. Fixing the antennas by hand is
sufficient.

6.6 Reset to factory settings
A reset to factory settings can be issued by the user with external hardware operation as described
below. The user configuration file will be overwritten with the factory default values. A new
configuration with Workshop System Management (WSM) will be necessary. Please refer to the
WSM User Guide [1] for more information about the configuration of ISAP. Please reset the ISAP only
if first level supports tells you to do so.
Figure 6-1: Reset to factory settings
Figure 6-2: Reset button
Follow these steps to reset the ISAP to the factory settings:
1.
Preferred: unplug the power cable, wait 5 seconds, reattach the power cable.
Alternative: if the ISAP is operational, push the reset button (see Figure 6-2) for at least
2 seconds, this will also reboot the ISAP.
2. Push the Reset button (see Figure 6-2) again and hold it down approximately 40 seconds
until ALL the LEDs of the ISAP flash several times.
3. The flashing of all LEDs indicates that the ISAP is set back to factory settings. Release the
reset button now.
Info!
After resetting to factory settings, the ISAP must be configured initially again through
Workshop System Management (WSM).
Info!
In case the READY LED did not switch over to constant yellow, the reset to factory
settings has failed; please try again.
