Chapter 1: Product Overview 1-11When the platform is in the Soft OFF state (refer to Advanced PowerManagement section that follows), receipt of a Wakeup Packet on theLAN can return the system to the ON state, if this feature is enabled bysoftware.Note: Due to limitations of the LAN controller and the OS, all featuresdescribed in the Network Device Class specification may not beavailable.100Base‐T is wired identically to 10Base‐T, except that the twisted paircable must be Category 5 and the hubs must permit 100 or 10/100 Mbpsoperation. Although 10Base‐T will operate on Category 3 twisted pair,or NCR “747” cable, an upgrade to Category 5 is required for 100Base‐T.A customer desiring to use the terminal in an existing 10Base‐Tenvironment can do so and simply run at 10 MB. In order to upgrade to100Mbps, Category 5 cable and 100 or 10/100 hubs must be installed.NCR strongly recommends the use of Category 5 for all new cabling,even if the customer initially intends to run only 10Base‐T.LED Indicators for Link Integrity (verifies cable and hub connection aregood) and LAN speed is provided on the Processor Board near the rowof connectors at the bottom of the e‐box. The LED is ON (yellow) whenthe speed is running at 100 Mbps.Link Integrity is provided to the PC chipset to permit boot‐up softwareto verify the presence of the LAN connection. Software must provide 2seconds after power‐up in order for the Link Integrity signal to becomevalid.Wireless LAN CommunicationsWhere a wired Ethernet connection is not desired a wireless LANadapter may be installed in the PCMCIA socket. This requires that thePCMCIA daughter‐card feature be installed. A wireless LAN used inthe terminal must meet the following requirements:
