Works with NetShutdown, a computer and server security shutdown program developed
by Huawei, to automatically shut down the computers and servers where NetShutdown is
installed to protect customer data and reduce loss.
Works with RCCMD, a client shutdown software developed by Generex, to
automatically and safely shut down the client that is installed with the RCCMD, thereby
protecting customers' data and preventing loss.
Alarm information is sent to the specified user mailbox at the specified time.
6.3 Modbus Card
The RMS-MODBUS01A provides an RS485 networking solution to remotely manage the
UPS.
The card implements the following functions by setting the DIP switches:
Selects the Modbus protocol by using a DIP switch over the RS485 communications
protocol.
Uses a DIP switch to select a two-wire or four-wire system.
Provides a DIP switch to select a build-out resistor.
Provides a DIP switch for setting the optional card address.
Supports hot swap.
6.4 Dry Contact Card
The RMS-RELAY01A is installed in an optional card slot and supports hot swap.
The dry contact card provides six alarm dry contact outputs (normal mode, battery mode,
bypass mode, low battery voltage, bypass backfeed, and UPS faults) and two dry contract
control inputs (one is the shutdown signal input, and the other is reserved).
6.5 External Dry Contact Card
The RMS-RELAY02B is connected to UPS together with SNMP card.
The external dry contact card provides four dry contact outputs (critical alarm, minor alarm,
mains mode, battery mode, bypass mode, inverter on, battery undervolt., bypass backfeed ,
high ambient tempreture, or UPS fault.) and two dry contract inputs (startup, shutdown).
The SNMP card, Modbus card, dry contact card, and external dry contact card are optional components
for communication. If these optional components are selected, their manuals are delivered with the
optional components.
