Operation Overview
Figure
shows the connections of LARA to its host, to peripheral devices, to the power source and to the local area network.
110/220V power
Figure 3.1.: LARA usage scenario
LARA redirects local keyboard, mouse, and video data to a remote administration console. All data is transmitted via IP. LARA can be used in a multi administrator and multi server environment as well. Combining one or several LARAs with a KVM switched matrix allows to access multiple servers on a single remote console.
LARA is multi user capable, i.e. up to 64 concurrent users may use LARA to administrate a remote site. Figure
shows a configuration with concurrent users on a number of servers connected by a KVM switching matrix using one or more LARAs.
Using more than one LARA in a configuration as shown in Figure
prevents blocking administrators who use the switching matrix.

Connecting LARA to the host system
In order to connect the KVM signals of the host system to LARA perform the following steps:
1. Connect the SUB-D 25 to PS2/PS2/Video cable to the SUB-D 25 connector on LARA
2. Connect the (purple) PS/2 Keyboard jack to the keyboard connector of the host system
3. Connect the (green) PS/2 mouse plug to the mouse connector of the host system
4. Connect the VGA HD-15 connector to the VGA monitor output of the host system
5. Connect the power supply as well as Ethernet and/or modem,ISDN, depending how you want to access LARA
In case you want to connect a local console to the host system besides LARA you may attach monitor, keyboard and mouse to the connectors on the front side. Figure
shows the resulting connections from LARA to the host system, whereas Figure

Connecting IPMI option
IPMI Version 1.5 defines a serial connection to access certain system parameters and to perform system actions like powering down the system or performing a hard reset. Modern server systems, supporting the IPMI V1.5 specification, provide a modus where the externally available COM2 serial connection can be configured as system management port (sometimes also referred to as emergency management port ). LARA may connect to this port in order to enable remote system management operations.
At http://developer.intel.com/design/servers/ipmi/index.htm
You will find further information about IPMI 1.5.
In order to use the IPMI over serial interface it has to be enabled in the host system. This can be done using BIOS settings or special utilities provided by the server manufacturer. Refer to the server manufacturer’s manual site to find out how the IPMI over serial line can be enabled and configured and where the IPMI serial port is placed.
Hint:
IPMI V1.5 is only supported by modern server systems. No server system manufactured before
2002 supports IPMI 1.5. By the date of printing this manual only the Intel SDS2 server main board has a proper support of IPMI Verson 1.5.
Connect the IPMI option serial cable to the RS232 port 1 on the rear side of LARA and to the serial port of the controlled system.

Additional cables are required in order to enable the remote reset and the remote power function of LARA:
1. Mount the reset/power bracket in a free slot of the controlled system.
2. Find the cable connecting the front panel reset button and the main board.
3. Disconnect this cable from the main board and connect it to the pin connector on the bracket as shown in Figure
.
4. Take the supplied red/black reset cable and connect the cable with one end to the main boards reset jumper connector (where you just disconnected the cable to the front panel) and with the other end to the bracket connector as shown in Figure
.
5. Find the cable connecting the front panel power button and the main board.
6. Disconnect this cable from the main board and connect it to the pin connector on the bracket as shown in Figure
.
7. Take the supplied red/black power cable and connect the cable with one end to the main board’s power jumper connector (where you just disconnected the cable to the front panel) and with the other end to the bracket connector as shown in Figure
.
8. Check the cabling: finally, there are four cables connected to the jumper connector on the bracket.
Now, connect the bracket to the LARA serial port 2 using the supplied SUB-D 9 to SUB-D 9 connector.
3.3.4.
Connecting the External Reset/Power Option
Please refer to the manual of the Peppercon external power switch option or a third party external power option to connect those external devices either to the Peppercon Reset/Power Connector or to the serial interface on the rear side of LARA.
3.3.5.
Connecting Ethernet
The rear side of LARA provides a RJ-45 connector for Ethernet. The connector is used either for a 100 Mbps 100BASE-TX connection or for a 10 Mbps 10BASE-T connection. The adapter can sense the connection speed and will adjust to the appropriate operation mode automatically.
14 CHAPTER 3.
INSTALLATION
10 Mbps Connection
For 10BASE-T Ethernet networks, the Fast Ethernet adapter uses Category 3, 4, or 5 UTP cable.
To establish a 10 Mbps connection, the cable must be connected to a 10BASE-T hub.
1. Make sure that the cable is wired appropriately for a standard 10BASE-T adapter.
2. Align the RJ-45 plug with the notch on the adapter’s connector and insert it into the adapter’s connector.
100 Mbps Connection
For 100BASE-TX Fast Ethernet networks, LARA supports Category 5 UTP cabling. To establish a 100 Mbps connection, the cable must be connected to a 100BASE-TX hub.
1. Make sure that the cable is wired appropriately for a standard 100BASE-TX adapter.
2. Align the RJ-45 plug with the notch on the adapter’s connector and insert it into the adapter’s connector.
Note:
The UTP wire pairs and configuration for 100BASE-TX cable are identical to those for
10BASE-T cable when used with Category 5 UTP cable.
3.3.6.
Connecting ISDN
The rear side of LARA contains two RJ-45 connectors. The upper connector, marked as ’ISDN’ is used to connect LARA to an ISDN network, using a standard ISDN cable.
