是这样,我们有很多WA4320-H20 这种型号的AP 之前是在AC-1 这台设备上线的,
然后我们新增了AC-2设备,我们就将一部分WA4320-H20 拿到AC-2去上线了,结果WA4320-H20 被升级了版本。
这些被升级了版本的WA4320-H20,再也无法回到旧的AC-1上线了。
============================
这种问题如何解决呢? 需要H3C你们的帮组。

如何将被AC-2升级了的WA4320-H20 恢复到 AC1 可以上线的原始版本呢?
如果没有办法恢复的话,你们可以发一份这个型号AP的BootROM 给我吗,非常感谢!
我的邮箱地址 
AC1:WX3520H-F,V7 R5208P03(老 V7,配套 AP 版本 Release2208P03、BootROM 7.08) AC2:WX3520X Comware9,把 AP 刷成 Release2455 + BootROM 升级到 7.27/7.28 ✅ 根本原因:BootROM 被向上升级了!新版本 BootROM 7.27/7.28 不再兼容旧的 Release2208P03 固件包 哪怕你把 AP 的 boot.bin、system.bin 强行刷回 2208P03,只要 BootROM 是 7.27/7.28,启动就会异常、CAPWAP 无法和 R5208P03 老 AC 建立隧道,这就是无法回 AC1 上线的根源。 关键点:BootROM 属于底层固件,H3C 官方不对外直接单独发放 BootROM 文件,网上也没有公开下载,我这边无法直接发 BootROM 给你,这个是红线。
两个事实区分清楚:
- AP 系统包(wa5300-boot.bin/wa5300-system.bin):2208P03 这个包本身可以找到;
- BootROM(Basic/Extend Bootrom 7.08):不能单独导出、不能单独下发,必须通过配套的、原厂完整的 AP 版本包(Release2208P03 整包)在 BootROM 模式下整机刷写,才能连带把 BootROM 降回 7.08; ⚠️ 但是:Release2208P03 这个老包本身,官方不再公开发放,只能通过 400 后台工单申请。
只有用这个配套的原厂完整 AP 版本包,在 AP 的 BootROM 菜单里刷入,才会同时把 BootROM 从 7.27/7.28 降级回 7.08 + 系统降到 2208P03。 只在 AP 正常 CLI 下用
tftp升级替换 boot/system bin,只能换系统,BootROM 不会降级,问题依旧,这个是绝大多数人踩的坑!
Ctrl+B进入 BootROM 菜单(现在 BootROM 是 7.27/7.28 版本的 Boot 菜单)✅ Full Image 升级:会同时刷 BootROM + boot.bin + system.bin,这一步才是真正的回退! ❌ 如果单独升级 boot/system,只是升级应用固件,BootROM 版本纹丝不动,刷完照样不能上 AC1。
display version核对:Basic Bootrom Version is 7.08
Extend Bootrom Version is 7.08
Release 2208P03
核对成功后,再放到 AC1 环境测试 CAPWAP 上线。
⚠️ 风险提醒:BootROM 降级属于底层降级操作,中途断电直接变砖,必须稳定供电!
设备型号:WA4320-H20 Ver.B 需求:申请配套 AP 版本 Release2208P03 完整 IPE 包,用于 BootROM 全镜像降级; 现象:AP 被 Comware9 WX3520X 升级到 Release2455,BootROM 升级为 7.27/7.28,该 BootROM 不兼容老 WX3520H-F(R5208P03),无法 CAPWAP 上线;需要全镜像包降级,把 BootROM 回退到 7.08。 备注:清楚该包是停产老版本,需要后台权限调取。
如果你 400 那边申请老包受阻、或者不想做 BootROM 降级(风险高、批量操作麻烦) AC1 是 WX3520H-F R5208P03,这个 AC 版本最高支持的 AP 版本就是 2208P03,不支持 2455,所以 2455 版本 AP 无法注册。 两个选择:
你是批量一批 AP 中招:
display version
#重点看Basic Bootrom / Extend Bootrom,必须都是7.08,只看Release号没用!
display wlan ap all
#放到AC1之后看能否正常建立CAPWAP隧道
H3C 的支持规范:BootROM 固件不单独分发,不通过邮件单独发送;必须依附对应版本完整 IPE 镜像包,走官方工单渠道申请。我这边没有权限提取、单独发放 BootROM 文件,还请理解。
