Port mapping For detailed port mapping information, see the HP BladeSystem Enclosure Quick Setup Guide or the HP BladeSystem Enclosure Setup and Installation Guide on the HP website (http://www.hp.com/go/bladesystem/documentation). Dual pass-thru modules In a dual pass-thru module configuration, two pass-thru modules in the HP BladeSystem c7000 Enclosure provide redundant paths to the network ports on the server blades. Redundant paths to server bays In a dual pass-thru module configuration, redundant Ethernet signals from each server blade are routed through the enclosure backplane to separate pass-thru modules within the enclosure. This configuration provides redundant paths to each server bay. Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate pass-thru modules within the enclosure. However, port to server mapping varies based on the type of server blade installed. XModem The pass-thru module supports XModem for transferring files during firmware upgrade using the serial management port. XModem sends blocks of data and includes an error-detection system called a checksum. When the data is received, the error detection system ensures that the entire message reached its destination. If not, the receiving computer sends a request for data retransmission. Introduction 6
