28Chapter 1: Installing the Emulation ProbeConnecting the Emulation Probe to a LANconfiguration switches” on page 28.Set all other switches to ON.5 Connect the power cord to the emulation probe.6 Verify that the power light stays on after 10 seconds.The IP address will be stored in EEPROM.7 Set switch S6 back to ON.Do this so that the emulation probe does not request its IP addresseach time power is cycled. The IP address is stored in EEPROM, soBOOTP does not need to be run again. Leaving this switch on willresult in slower performance, increased LAN traffic, and even failure topower up (if the BOOTP server becomes inactive).8 Verify your emulation probe is now active and on the network.See “To verify LAN communications” on page 29.See Also For additional information about using bootpd, refer to the bootpd(1M)man page.To set the 10BASE-T configuration switchesSet switches S7 and S8 to ON unless one of the following conditions istrue:• If the LAN cable exceeds the standard length, set switch S7 to OFF.The emulation probe has a switch-selectable, twisted-pair receiverthreshold. With switch S7 set to OFF, the twisted-pair receiver threshold islowered by 4.5 dB. This should allow you to use cable lengths of up toabout 200 meters. If you use a long cable, you should consult with yourLAN cabling installer to ensure that:• The device at the other end of the cable has long cable capability, and• The cable is high-grade, low-crosstalk cable with crosstalk attenuationof greater than 27.5 dB.
