Booting The Switch With Dual Images - 3Com LS8M1P12TEH Installation Manual

Installation Manual
H3C S7500 Series Ethernet Switches
After the system reboots, load the Boot ROM to the LPUs through command lines.
For more information, refer to section 7.4.1 "Loading Through Command Lines"
on page 7-14.
Caution:
The software of the SRPUs and LPUs must be consistent so that the S7500 series
can work normally.
After loading the host software of the SRPUs of the S7500 series, you must reboot
the LPUs to synchronize the software of the LPUs with that of the SRPUs.
The S7506R supports dual SRPU design and active-standby switchover. If two
SRPUs are equipped, you can use the active-standby switchover function to update
and reboot the two SRPUs in turn on condition that one SRPU works normally.
Although the SRPUs support hot backup, you are recommended to reboot the
whole system after loading the software of the SRPUs because LPUs must be
rebooted to keep their software version consistent with that of the SRPUs and the
services will be interrupted during LPU reboot.

7.5 Booting the Switch with Dual Images

The S7500 series support dual image booting. That is, the switch normally boots with
