When using the device in pair, if the device at the client side is in a FM001-1 single-slot
chassis, the device in “auto-recognition” mode will switch to the “force remote” mode
automatically. If the device at the client side is in a FM002-16 16-slot chassis, the users have
to set the network management mode of the device to “force remote” mode manually. For the
device at the central site, if local management is required, please set the network management
mode of the device to “auto-recognition” mode.

Please note that when using the device in pair and both of the devices are in FM002-16 chassis, one of
