Connect an Ethernet Cable

1. Connect a computer running a Microsoft Windows operating system (Microsoft Windows
[64-bit] or SP3 [32-bit] or later) to the card by plugging a network cable into the RJ-45 port on the
computer and the Liebert IntelliSlot Unity card.
2. Autoconfiguration, which is normally enabled on computers running Microsoft Windows operating
systems, will automatically negotiate the communication settings. This takes about one minute.
NOTE
If the computer does not automatically connect, verify that autoconfiguration is enabled by:
Open the Command Prompt window from the computer's Start menu.
Enter ipconfig/all to verify that Autoconfiguration is enabled on the computer and that an
Autoconfiguration IPv4 Address has been assigned: Enabled = Yes (see Figure 2-1). An
Autoconfiguration IPv4 Address begins with 169.254.)
3. If the Ethernet adapter being used to attach to the card does not show an Autoconfiguration IPv4
Address, open a new Command Prompt and type ipconfig/renew and press Enter. This forces the
computer to acquire an Autoconfiguration IPv4 Address.
4. When the computer has an Autoconfiguration IPv4 Address, open a browser window on the computer
and type 169.254.24.7 (the card's default Autoconfiguration IPv4 Address) in the URL address field.
The card's Web page will appear.

Connect an RS-485 Serial Cable

For Building Management Systems using serial network connections, an RS-485 serial cable connection
will be used.
Liebert IntelliSlot Unity cards come with an Adapter RJ-45-2POS Terminal Block. The adapter has two
screw terminals to attach the ends of a RS-485 cable for communicating to a building management
system.
1. Find the serial cable from the building management system. If it already has an RJ-45 connector on
the end, determine whether it uses the same pin-out as the Liebert IntelliSlot Unity card's connector. If
the pin-out is the same as the Liebert IntelliSlot Unity card connector's pin-out, skip to Step 7.
2. Strip the ends of the positive (typically red) and negative (typically black)
leads on the RS-485 cable so that enough bare wire is exposed for
connection, about 1/4" (6mm).
NOTE
No bare wire should be exposed when the connection is completed.
3. Position the adapter so the side with the positive and negative marks is
face up. The small markings are on the same side as the screw heads, as
shown at right.
