某局点WA4320-ACN-SI升级版本提示内存空间不足经验案例

某局点反馈AC（型号WX3510H）升级至V7的R5215P01版本以后，出现个别AP(型号WA4320-ACN-SI)注册失败。AP 原版本是出厂很老的版本，Boot7.02。Console登录问题AP 发现提示内存空间不足，下载版本失败。

WA4320-ACN-SI这款AP设计的Flash大小 是16M。早期这款AP V7的 ipe版本大小约为12MB多。正常情况下格式化AP 以后可以释放15MB左右的Flash空间。当这款AP 从V5 升级至V7 较老版本，或者出厂就是较老的V7 版本（Boot 7.04）以下时，再升级至V7 较新版本（例如R5215P01版本）就会概率性出现内存空间不足的问题，导致下载版本失败。

格式化AP 以后在bootware菜单下查看flash也只有12MB多。

而在AC 上查看R5215P01版本涉及的WA4320-CAN-SI的AP的ipe文件比较大，已经超过了13MB。

<WX2510H>dir

Directory of flash:/apimge                                                                                                                            

   4 -rw-    13158400   Jan 01 2011 08:00:42   wa4300s.ipe

所以即使将AP格式化操作以后所剩Flash空间也只有12MB多，存在内存不足，下载版本失败。

将AP的Boot手动升级到7.04以上解决（因为是概率性出现，所以涉及的AP数应该不多，可以手动升级解决）。

下面是升级AP Boot的操作过程。由于AP 的Flash空间有限，不能再上传ipe文件升级Boot，可以上传btw文件进行boot升级。btw文件可以找售后技术人员获取。

以下Bootware菜单操作下通过btw文件升级Boot的操作指导。

1. 对于AP升级失败的问题，最快的排查方法就是找到这台AP，直接Bonsole登录查看AP 从启动到注册时段打印的信息，找到问题点。

2. 对于WA4320-ACN-SI这款AP 由于设计的Flash比较小，升级版本时可能会因为Boot太老概率性地出现内存空间不足的问题。建议如果AP 是从V5 升级至V7 版本时不要选择太老的版本，最好是升级到Boot7.04以上的配套版本。
