Question

当TS3500需要配置双机械手（accessor）时,需要配置HA1单元时，首先在L53或L23里需要配置下列产品号：
    fc#1690 - Advanced Library Management System (if not already present)
    fc#9003 - Additional Expansion Frame Attachment (at least one additional frame to serve as Service Bay B)

    其次需要配置一个空的D53或D23机柜，和HA1机柜一起来作为第二个机械手的Service Bay.在空的D53或D23里需要配置下列产品号：
    fc#1440 - Service Bay B Configuration and Second Accessor

    然后还需要在某一个D53或D23机柜里（不能是作为第二个机械手Service Bay的D53或D23）配置下列产品号：
fc#1451 - Enhanced Frame Control Assembly (which includes two power supplies and a redundant AC line feed for the accessor)
