The RXE-100Remote Expansion Enclosure is a modular design that as a base unit contains aminimum of 6 full length PCI-X slots. An additional 6 full length PCIX slots can beadded to attain the total of 12 PCI-X slots.RXE Management portA second cable is attached to the RXE management port (RJ-45) to provideenvironmental control communication between the host system and the RXE-100Remote Expansion Enclosure.Ethernet portThe server comes with an integrated Ethernet controller. This controller provides aninterface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex(FDX) capability, which enables simultaneous transmission and reception of data onthe Ethernet local area network (LAN).The following illustration and table show the pin-number assignments for theEthernet connector. These assignments apply to both 10BASE-T and 100BASE-TXdevices.1 8Link LED(green)Tx/Rx LED(amber)Table 13.
