Remote Loading Using Tftp - H3C S7500 Series Operation Manual

Operation Manual – System Maintenance and Debugging
H3C S7500 Series Ethernet Switches
Note:
The steps listed above are performed in the Windows operating system, if you use
other FTP client software, refer to the corresponding user's guide before operation.
Only the configurations steps concerning loading are illustrated here, for detailed
description on the corresponding configuration commands, refer to the chapter
"FTP and TFTP".

1.3.2 Remote Loading Using TFTP

The remote loading using TFTP is similar to that using FTP. The only difference is that
TFTP is used instead off FTP to load software to the switch, and the switch can only act
as a TFTP client.
Caution:
SRPU software and LPU (line processing unit) software must be identical.
Otherwise S7500 Ethernet Switches cannot work normally.
To keep the software of SRPU and LPU identical, you need to restart the LPU after
you upgrade the host software of the SRPU of the S7500 series Ethernet switches.
S7506R switches feature the double SRPUs and active-standby switchover function.
If a switch possesses two SRPUs, with the active-standby switchover function
enabled, you can in turn upgrade and restart the two SRPUs with one SRPU being
active. Although SRPU can be upgraded through hot backup, because the LPU
must be restarted to keep identical with the SRPU's software, your services will still
be interrupted during the LPU restart period. Therefore, you are recommended to
restart the whole switch straight after you upgrade the host software of the SRPU of
the S7506R switch.
