The Sun Blade 150 contains a network interface card (NIC) to communicate with the LAN.
A Category 5 (UTP-5 "data grade") cable from a LAN switch or hub is connected to the twisted-pair Ethernet (TPE) connector on the back panel of the Sun Blade 150 platform (location 4 in the diagram below).
For information about signals at the TPE connector, see the "Twisted-Pair Ethernet Connector" section in the "Signal Descriptions" chapter of the Sun Blade 150 Service Manual.
The Sun Blade 150 is set to auto-detect network speed and duplex. Avaya recommends setting the LAN switch or hub to auto-detect for optimal performance. If the LAN switch or hub is set to a specific speed, administer the NIC on the Sun Blade 150 to match that speed. For information on how to administer the NIC, see System Administration Guide, Volume 3 from Sun.
