如果有在很快将超时)的您的ESA (或一个的一个过期的证书，您能更新当前证书：

1. 下载证书签名请求(CSR)文件。
   
   
2. 提供CSR文件给您的Certificate Authority (CA)并且请求加强保密文件(PEM) (X.509)签名证书。
   
   
3. 通过在部分描述跟随的其中一个方法更新您的当前证书。

为了开始，请导航对从设备GUI的网络>证书。打开您的证书并且通过在下镜像显示的链路下载CSR文件。如果ESA是集群的成员，您必须验证其他集群成员证书和使用同一个方法每计算机。使用此方法，专用密钥在ESA。最后一步是安排证书签字由您的CA。

示例如下：
