Operation Manual – System Maintenance and DebuggingH3C S7500 Series Ethernet SwitchesChapter 1 Boot ROM and Host SoftwareLoading1-18Note:z The steps listed above are performed in the Windows operating system, if you useother FTP client software, refer to the corresponding user’s guide before operation.z Only the configurations steps concerning loading are illustrated here, for detaileddescription on the corresponding configuration commands, refer to the chapter“FTP and TFTP”.1.3.2 Remote Loading Using TFTPThe remote loading using TFTP is similar to that using FTP. The only difference is thatTFTP is used instead off FTP to load software to the switch, and the switch can only actas a TFTP client.Caution:z SRPU software and LPU (line processing unit) software must be identical.Otherwise S7500 Ethernet Switches cannot work normally.z To keep the software of SRPU and LPU identical, you need to restart the LPU afteryou upgrade the host software of the SRPU of the S7500 series Ethernet switches.z S7506R switches feature the double SRPUs and active-standby switchover function.If a switch possesses two SRPUs, with the active-standby switchover functionenabled, you can in turn upgrade and restart the two SRPUs with one SRPU beingactive. Although SRPU can be upgraded through hot backup, because the LPUmust be restarted to keep identical with the SRPU’s software, your services will stillbe interrupted during the LPU restart period. Therefore, you are recommended torestart the whole switch straight after you upgrade the host software of the SRPU ofthe S7506R switch.
