Performance ConsiderationsNokia 500s Installation Guide 75maximum system throughput. Each 6U PMC card carrier unit has a separatePCI bus connection to the main system motherboard. In the configurationdescribed here, each of the two copper dual-port Gigabit Ethernet NICs accessa separate PCI bus.For the 500s appliance, any two NICs installed on a single PMC carrier bothoperate at the PCI frequency of the least capable NIC installed.Copper Gigabit Ethernet NIC FeaturesThe copper Gigabit Ethernet NIC supports: High bandwidth Full-duplex mode operation up to 1 Gbps Link speed auto advertising (10/100/1000) Hot swapping PCI operation at 33 MHz, 66 MHz, and 100 Mhz Compliance with IEEE 802.3z and 802.3ab Gigabit Ethernetspecifications Cable autosensingYou can configure and monitor Gigabit Ethernet NIC interfaces with NokiaNetwork Voyager. Specifically, you can use Network Voyager to set the portspeed and full-duplex mode to 1000, 100, or 10 Mbps.For information about how to access Network Voyager and the relatedreference materials, see “Accessing Nokia Network Voyager ReferenceInformation” on page 52.
