Technical Data656.5 Technical Data of the Communication PortsThe first versions of the CMC 356 test sets were delivered with a NET-1board that contained two different Ethernet ports: ETH1, a10/100Base-TXEthernet port and ETH2, a 100Base-FX (optical fiber) Ethernet port.With the introduction of the front panel control device CMControl, theCMC 356 test sets were then equipped with a NET-1B board that containedtwo identical 10/100Base-TX PoE (Power over Ethernet) Ethernet portsETH1 and ETH2.Today, the standard interface is the NET-1C board that, in addition to ETH1and ETH2, provides an additional USB port.CMC 356 test sets with NET-1 board can be upgraded with the new NET-1Cboard to be able to communicate with the new CMControl and haveEthernet as well as USB access at the same time.6.5.1 The NET-1C BoardTable 6-21:Technical data of theNET-1C communicationports USB andETH1/ETH2NET-1C: USB port and Ethernet ports ETH1/ETH2USB type USB 2.0 full speed up to 12 Mbit/sUSB connector USB type BUSB cable 2 m USB 2.0 high speed type A-BETH type 10/100Base-TX (10/100Mbit,twisted pair, auto-MDI/MDIX orauto-crossover)ETH connector RJ45ETH cable type LAN cable of category 5 (CAT5)or betterETH statusindicationGreen LED: physical link presentYellow LED: traffic on interfaceETH Power overEthernet (PoE)IEEE 802.3af compliant.Port capability limited to one Class 1(3.84 W) and one Class 2 (6.49 W)power device.
