锐捷ruijie S86升级10.4（3）软件，提示File is Too Long! Failed 或者The binary file crc was not correct

1）现象

a.8610，原来软件版本RGOS 10.4(2b3) Release(102059)，用S8600_V10.4(3)_R118208_CMII.bin升 级包，升级总是失败

b.主程序下通过copy tftp升级，提示File is Too Long! Failed!

Ruijie#copy tftp://192.168.1.110/rgos.bin flash:rgos.bin

The binary file crc was not correct. Delete it...

2）原因

a.RGOS 10.4（3）以前的软件版本，存在tftp协议无法传输超过32MByte大小的文件，所有无法传输 S8600_V10.4(3)_R118208_CMII.bin这个有近35MByte的文件；

b.S8600_V10.4(3)_R118208_CMII.bin升级包是适用于EC类线卡的，从提示的报错信息来看，应该是软件版本错了，如果没有EC卡，应该升级S8600_V10.4(3)_R118208_NOEC_CMII.bin升级包

3）解决方案

86如果原来是非10.4（3）的版本，同时有EC线卡，那么升级的顺序应该先整机升级S8600_V10.4(3) _R118208_NOEC_CMII.bin（该文件适用于打破tftp协议的32Mbyte限制），重启，成功后再升级适用 EC卡的S8600_V10.4(3)_R118208_CMII.bin。
