Dial-Up Modem Connection
The Management Interface includes Z Modem functionality for the DB9 dial-up management console port.
An external modem attached to the DB9 port (not included with unit) will be required to dial into the
management console interface of the EXTender. This console interface will allow remote dial-up access
using Z modem protocol to the management console.
Additionally, when a dial-up connection has been established to the management interface of one unit, it
will be possible to then “Rlogin” to other connected units in order to access the management interface of
those units.
