升级6800firmware的具体步骤：
1、 首先配置好6800sc的网络地址，保证笔记本和sc的ip地址在同一网段，sc访问到笔记
本；
2、 从eiscd上面找到最新的firmware版本，这次升级的是5.18版本； 3、 在笔记本上面建立一个http服务，把对应的firmware升级文件解压拷贝到该默认目录下； 4、 执行如下命令，升级firmware（注意：以往都是利用ftp服务进行升级，但是这次通过
ftp出现了错误，错误信息如下：
“F6800:SC> flashupdate -f ftp://down:down@192.168.0.88/1 all
flashupdate: failed, ftp://down:down@192.168.0.88/1/sgsc.flash: cannot open file F6800:SC> flashupdate -f ftp://down:down@192.168.0.88/1 systemboards
flashupdate: failed, ftp://down:down@192.168.0.88/1/sgcpu.flash: cannot open file F6800:SC> flashupdate -f ftp://down:down@192.168.0.88/down/1 all Error reading file: ftp://down:down@192.168.0.88/down/1/sgrtos.flash F6800:SC> flashupdate -f ftp://down:down@192.168.0.88/down/1 all”
实际ftp服务可用，但是为何出现这样的错误还没有找到原因，最后通过http服务升级成功，所以如果今后要升级firmware，建议都要ftp和http服务都要准备）
F6800:SC> flashupdate -f http://192.168.0.88/ all
As part of this update, the system controller will automatically reboot. RTOS will be upgraded automatically during the next boot. ScApp will be upgraded automatically during the next boot.
After this update you must reboot each active domain that was upgraded.
Rebooting will interrupt any current operations. This includes keyswitch changes, Solaris reboots and all current connections.
Do you want to continue? [no] yes
Waiting for critical processes to finish. This may take a while. Critical processes have finished.
