Special Notes for Management Adapters Intel EtherExpress(TM) PRO/100+ Management Adapter Feature Notes ================================================================ Note: the information in this file applies to Intel management adapters only. Standard, non-management adapters do not have a 3-pin auxiliary power connector. 1.

Intel LANDesk( Service Agent Description Operation Troubleshooting LSA Wake on LAN =========== Description The Wake on LAN (WOL) feature of the PRO/100+ Management adapter allows a Wake on LAN enabled computer to be powered-on remotely by a network management program. In some operating systems, it can also wake the computer from suspend mode. This is accomplished by sending a special type of data packet containing the adapter's specific Ethernet address. The PRO/100+ Management adapter is supplied with a small cable with a 3 pin connector at each end. One end of the cable is attached to the adapter, and the other end is attached to the 3 pin WOL connector on the WOL enabled computer. As long as AC power is available to the power supply, the adapter will draw +5 volt standby power through the cable when the machine is powered off, allowing it to "listen" to the network for a wake up packet. If the cable is not attached, the Wake on LAN function will not be available and the adapter will operate as a standard non-management PRO/100+ adapter. Computer requirements Only a computer designed for Wake on LAN can use this function. It must have a 3 pin connector that matches the 3 pin cable supplied with the PRO/100+ Management adapter. If the computer has a Wake on LAN connector that does not fit the 3 pin cable, do not attempt to use it with this adapter. Attempting to do so could cause permanent damage to the computer. The +5 volt standby power supply must be capable of supplying at least 0.6 amps (600 milliamps) at +5 volts. This value is usually listed on the power supply label as +5SB, +5VSB or +5AUX. WOL Settings in Microsoft Windows* 98 If the PRO/100+ Management adapter is installed in Microsoft Windows 98, you will have an additional setting in the adapter properties that is not available for other types of PRO/100+ adapters. This setting is titled "ACPI Wake On LAN" and by default is set to "Enabled". You may need to change this setting to "Disabled" if you are using the PRO/100+ Management adapter in a Wake on LAN enabled computer that is not ACPI compliant. Check your computer owner's manual or contact your computer vendor to determine if your computer is ACPI compliant. Settings in the computer's BIOS Wake on LAN enabled computers typically have settings similar to the following: On Modem Ring Stay Off On LAN Power-on On PME Stay Off The setting "On LAN" refers to wake-up events received through the 3 pin WOL connector. The setting "On PME" refers to wake-up events received through a signal on the PCI bus defined as "Power Management Event". The PRO/100+ Management adapter is capable of using either of these methods. Which settings to use will vary with the computer and operating system. The following are suggestions only. A. In ACPI compliant computers running Windows 98, set the "On LAN" BIOS setting to "Stay off" and the "On PME" BIOS setting to "Power-on". In other operating systems, or in computers that are not ACPI compliant, set the BIOS setting "On LAN" to "Power-on" and the BIOS setting "On PME" to "Stay Off". B. If these settings do not work for you, try reversing them, or set both to "Power-on". Troubleshooting Wake on LAN Note: The reception of a wake up packet will set the adapter to a special state. This condition must be reset before the adapter will accept another wake up packet and power-on the computer. The drivers for this adapter are written to reset this condition when they load. The only other way of resetting this condition is removing AC power from the computer for a short duration (~10 seconds). Once you have sent the computer a wake up packet and powered-on the computer, you must let a driver load or it will no longer accept any wake up packets. If this happens, you can remove the AC power cord for 10-15 seconds or load an adapter driver to reset the adapter and restore normal operation. If the computer will not power-on when a wake up packet is sent, check the computer's BIOS for power settings (see "Settings in the computer's BIOS" above). If you are connected to a hub or switch, the link LED on the back of the adapter should be on, even though computer power is off. If the link LED it is not on, try powering the computer on. If the LED now lights, then the adapter is not receiving power in standby mode. If this is the case, check to make sure the 3 pin cable is properly plugged into a standard WOL 3 pin connector. Make sure that the power supply is capable of supplying the necessary current (see Computer Requirements above). Also, check with your computer vendor to be sure that the computer is, in fact, capable of supporting Wake on LAN. If the link LED does not come on when the computer is powered-on, you have not established link with your hub or switch. Check your cabling or substitute a known good cable. Make sure your hub or switch is either 10baseT or 100baseTX and is powered-on and fully functional. If your computer will not power-on at all when the 3 pin cable is attached, but will power-on when the 3 pin cable is removed, your +5 volt standby power supply is possibly insufficient (see Computer Requirements above). If everything listed above is correct and the computer will still not respond to a wake up packet, check with your computer vendor for an updated BIOS. Intel LANDesk Service Agent (LSA) ================================= Description The LSA is a utility program that is stored in a flash memory chip on the adapter. This utility will execute when the computer is first powered-on. It will attempt to obtain an IP address from a DHCP or BOOTP server and locate a program image file to download and execute. This feature is intended for use in conjunction with network management software (such as Intel LANDesk products) to automatically configure newly installed computers. Computers do not need to be Wake on LAN enabled to use this feature, and it will work with or without the 3-pin auxiliary power connector attached. Operation When the LSA executes, you should first see the message "PXE-M04 Hooking Bootstrap Interrupt 19h" appear on the screen. After this times out, it should then attempt to locate a DHCP or BOOTP server. If it can not locate a DHCP or BOOTP server or cannot locate an image file to download, it should time out and the computer should continue to boot normally. If it does download an image, you may be presented with additional options. This sequence can be manually interrupted by pressing Escape or CTRL-C. The LSA can use bootstrap interrupt 18h or 19h. To change the interrupt, press Ctrl-T when the message "PXE-M04 Hooking Bootstrap Interrupt 19h" appears on the screen. This change will be automatically saved to the adapter. If you are not using the correct bootstrap interrupt for your computer, it will boot from the next available boot device immediately after the "PXE-M04" message times out. The bootstrap interrupt is not related to the hardware interrupt (IRQ) assigned to your adapter. Troubleshooting LSA If you do not see the message "PXE-M04 Hooking Bootstrap Interrupt 19h", check the following; In the computer setup, check for the boot device sequence. If "LANDesk Service Agent" or "Network" is listed, move it ahead of the hard drive in the boot sequence. Some computers require manual intervention to execute the LSA. Look for an informational note on the computer monitor after power-on that may instruct you on executing a network boot. For example, some Compaq computers will display the message "F12 Network Service Boot" on the Compaq banner screen. * Other trademarks and brand names are the property of their owners.
