Only USB devices are supported. For attachment to an Advanced Connectivity Technology (ACT) KVM switch, a new USB Conversion Option (part number 73P5832) can be used. This smart cable is plugged into the USB and video ports on the server and it converts KVM signals to CAT5 signals for transmission over a CAT5 cable to either a Remote Console Manager (RCM) or Local Console Manager (LCM). The x455 can then be managed on the same set of switches as PS2- or C2T-based KVM servers. The x455 includes a dedicated external serial port. During the boot process, the port acts as an auxiliary console for the EFI. After the operating system has booted, the port is dedicated to the operating system as COM1. The RXE Expansion Ports provide connectivity to a RXE-100. Either a single cable in port A or two cables to both ports are supported. Using two cables provides redundancy as well as additional throughput. There are two RJ-45 ports providing Gigabit Ethernet connectivity, as shown in Figure 3-4. A third RJ-45 Ethernet connector is also on the Remote Supervisor Adapter. This connector is only used to connect to the Remote 66 IBM xSeries 455 Planning and Installation Guide Eserver
