Use direct cable for connection to the Ethernet switch.
SNMP port connector
An RJ-45 female socket is used for Ethernet port connection (10Base-T, IEEE 802.3
standard) for control over the SNMP protocol, shown above (see “Ethernet” port
connector”).
Use direct cable for connection to the switch.
Console port connector
A DB-9 (female) connector is used for console connection. The console port has a standard
RS-232 DCE interface, and utilizes the following settings: asynchronous mode, 9600
baud speed, 8 bits/symbol, 1 stop bit, no parity. Use a direct cable for connection to a PC
COM port.
!
An RTS signal from the controlling terminal to the device port must be
provided when connecting the console.
It is recommended to use the following cable diagrams:
