Goal• LARA™ enables

seamless integration of power /reset control in a HTML based remote management environment

• Besides Keyboard, Video, Mouse and Serial Interface Power Management becomes vital part of a remote Management infrastructure

Three Options• Power management can be done in different

ways. Peppercon covers a variety of power management options. Three different options are available now:– In case the server offers an IPMI (Intelligent Platform

Management Interface) Version 1.5 or higher, Peppercon will integrate the IPMI power and reset functionality.

– The internal Power Management Option offers reset and power management by placing an additional PCI bracket into the system.

– An external power switch box can be used to turn on/off the system in case no internal interface is available or accessable

Controlled by LARA

All LARA Power Management Options are connected to the LARA

device by a serial RS 232 connector (SERIAL 2) on

the back

A bracket is placed in an empty bracket slot. Internal wires connect the bracket with the power and reset pins of the main board. In case there is only a single front panel connector to aggregate the font panel signals including power and reset signal – Peppercon provides all necessary adaptation kits

Front Panel Connectors

• Single pins always available on off-the-shelf mainboard (Asus, Giga, Chaintec, Spacewalker, ...)

• No single pins for reset/power in– Bar bone systems (mainboard and casing together from one

manufacturer)• Intel Servers• Siemens • HP• Compaq • IBM• Super Micro• Dell

– Usually single or double row jumper connector is used

Compaq DL 380 (1x6 pin)

IPMI Option

• Modern Servers (Intel-OEM Devices from platform STS-2, HP, Siemens) are equipped with a serial management Port (RS232), also called EMP (emergency management port)

• LARA supports the IPMI protcol on the EMP, enabling Reset and Power management.

Peppercon Inline Power Switch Module

• Peppercon offers a 0U external Power Switch option for 110 …220 V Power. The switching box is „always on“, which means that in case the system fails, power is turned on.

• The switch module is powered by the net current itself, so no additional battery or power supply is needed.

Third Party Power Switch

• Currently, there are lots of external power switching devices available on the market, among which are products from vendors like– BayTec– Avocent/Equinox– Moxa– ServerTech/Sentry

• Peppercon supports Third Party Power Switching devices either explicit using the HTML user interface or implicit using a generic serial terminal emulation

Explicit Support• The most convenient way is given if the

Power Switch support is explicitly integrated. Such integration is available for– Avocent SPC 800– ServerTech/Sentry PDPT– ePowerswitch (Leunig, Neol,…)

• Peppercon is willing to enhance explicit support for power management options to dedicated products if requested

• On the html interface page „Serial Settings“ the support for one of the devices has to be turned on. The device itself is connected to LARA using the SERIAL 2 interface connector

Implicit Support• The so called Pass-Thru Mode of LARA™

allows to control virtual any power switching module with serial control interface.

• On the html interface page „Serial Settings“ the Pass-Thru mode has to be turned on. The device itself is connected to LARA using the SERIAL 1 interface

connector

LARA™ plus KVM-Switch

• LARA is optimized to be used together with third party KVM switches. The KVM switch is connected to the KVM input interface

• LARA among others supports KVM Switches of the following suppliers– Avocent/Cybex/Apex– Rose– Belkin– Aten and OEMs– Rextron– Adder– NTI– CCC– Raritan

Support of Multiple Power Switches• To enable controlling of several

servers via KVM and Power/Reset, the external power switch device has to provide multiple power switch channels. Peppercon recommends ePowerSwitch, because there areup to 4 times 8 Port Power switches stackable.

• The ePowerSwitch is explicitly supported by LARA. After enabling the ePowerSwitch support users have to assign the power channels to the different KVM channels. This ensures that only this very server, controlled by the KVM switch will be turned off/turned on or will receive a hard reset.

Power over KVM

Peppercon‘s unique technology* allows the

usage of a standard KVM to distribute Power control

and reset signals to numbers of servers and

devices

* Worldwide Patent pending

How it works

The solution is designed on a single port basis. It can be scaled up easily whenever you want to add another computer without the limitations normally experienced when using other power control products.

To connect the Power Management device, a PS/2 Passthrough device is placed in line with the PS/2 cable from the KVM switch to the keyboard of the Computer. This device has a cable with a DB9 plug that can then be connected to the standard LARA power management options.
