2.1.3 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 pinout as the Liebert IntelliSlot Unity card’s
connector. If the pinout is the same as the Liebert IntelliSlot Unity card connector’s pinout, skip
to Step 6 .
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).
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.
4. Loosen the screw to the positive terminal and insert the red wire far
enough to insert the bare wires into the terminal block under the screw, then tighten the screw.
Be careful not to break the wires.
5. Repeat Step 3 with the negative terminal and the black wire.
6. Plug the cable into the 485 RJ-45 port on the Liebert IntelliSlot Unity card.
2.2 Change User Names and Passwords Immediately
Emerson recommends changing the administrative user name and password immediately to
safeguard protected configuration and control areas of the Liebert IntelliSlot Unity card.
The user name and password are set at the factory; each is
Liebert (case-sensitive). All printable
characters are valid except \ : ’ < > ~ ? " #
A general user name and password are also set at the factory:
User and User (case-sensitive). This
may be left at the factory default or changed. The general user has access only to non-protected
configuration and control areas of the Liebert IntelliSlot Unity card.
To change the default user names:
1. Select the Unity Tab > Configuration > User Settings.
2. Click the
Edit button and enter the factory-set user name ( Liebert ) and password ( Liebert ).
3. Click OK .
4. Enter a new administrator user name and password.
5. Re-enter the administrator password to confirm it.
Optional General User Name Change
6. Enter a new general user name and password.
7. Re-enter the general user’s password to confirm it.
8. Click the
Save button to confirm the changes or click Cancel to discard them.
NOTE
No bare wire should be exposed when the connection is completed.
NOTE
Record the new user names and passwords and save them in a secure place where they can be
found if forgotten.
