Interconnect management cable, for remote I/O management. The RXE-100 ships with a 3.5 m cable. Two lengths are available: - 3.5 m interconnect management cable kit (part number 31P6087) - 8 m interconnect management cable kit (part number 31P6088) Use the 8 m versions of each of these cables if the distances between the two devices warrant the extra length (for example, in separate racks). Important: This interconnect management cable has standard RJ-45 connectors, but it is not wired the same as an Ethernet or crossover cable. Ensure that the proper cable is used to connect the server to the RXE-100. The management cable has two twisted wire pairs: Pins 2 and 3 connect to one pair, pins 7 and 8 connect to another. With the Ethernet cable, the wire pairs are connected to the following pins: 1 and 2, 3 and 6, 4 and 5, 7 and 8. Power to the RXE-100 enclosures is controlled by the servers via the interconnect management cable and under the control of the Remote Supervisor Adapter. The following connections to the RXE-100 are supported: One server connecting to a six-slot RXE-100 One server connecting to a 12-slot RXE-100 A two-node server connecting to one shared RXE-100 Two standalone servers connecting to one shared RXE-100 Four-nodes connecting to one or two RXE-100s One server connecting to a six-slot RXE-100 When the RXE-100 has only six PCI-X slots installed, connect a single RXE management cable and a single RXE data cable, as shown in Figure 3-8 on page 73. 72 IBM xSeries 455 Planning and Installation Guide Eserver
