Connecting The Network Cable - Black Box PS568A User Manual

The Rackmount Remote Power Manager can be controlled via a TCP/IP network,
controlled by a local PC that communicates with the unit via cable, or controlled
via an external modem. To switch plugs or select parameters, commands are issued
to the power manager either via the network or via the COM/RS-232 port.
You don't need to connect both the network and COM/RS-232 ports.
The COM/RS-232 port can be connected to either a local PC or an
external modem.
• Network port: Connect your 10BASE-T or 100BASE-T network interface to the
Rackmount Remote Power Manager's network port. For more information,
refer to Section 3.4.
• Local PC: Use the supplied null-modem cable to connect your PC COM port
to the power manager's COM/RS-232 port. Make sure that the serial port
mode is set to console as described in Section 4.3.3.
• External modem: Use a standard AT
external modem to the power manager's COM/RS-232 port. Make sure that
the modem is initialized at the same default parameters as the COM port. Be
certain that the serial port mode is set to modem as described in Section 4.3.3.

3.4 Connecting the Network Cable

The network port is an RJ-45 Ethernet jack for connection to a TCP/IP network.
Connect your 10BASE-T cable to the network port. The power manager includes a
default IP address (192.168.168.168) and a default subnet mask (255.255.255.0).
When installing the power manager in a working network environment, we
recommend that you define network parameters as described in Section 4.3.4.
The Rackmount Remote Power Manager features a 10BASE-T interface.
If you're connecting a router switch to the Rackmount Remote Power
Manager, note the following: When connecting to a 100BASE-T
interface, most router switches will autosense to determine if the device
is 100BASE-T or 10BASE-T and configure the network interface
accordingly. If your router switch does not autosense, the network
interface port must be manually set to 10BASE-T.
