Installing a Remote Management Unit
When installed, the library will detect the presence of the RMU. However, you will need to set the
IP Address, Subnet Mask, and Gateway Address before the RMU will function. After you have
installed the RMU, see the instructions provided in Configuring the RMU
on configuring it.
Step 1 Remove the RMU from the packaging.
Step 2 Power down your Scalar 24 and disconnect the AC line cord from the AC source
outlet.

Step 3 From the rear of the Scalar 24, locate the available RMU slot. Loosen the thumbscrew
on the cover plate and remove the cover plate. Store the cover plate in a convenient
place. It is required for proper operation and cooling of the library if the RMU is ever
removed.
Step 4 Slide the RMU into position and tighten the thumbscrew.
Step 5 Plug the power cord into a grounded electrical socket.
Step 6 Connect the network cable to the RMU.
Step 7 Power on the Scalar 24.

Removing a Remote Management Unit
Follow these steps to remove a Remote Management Unit.
Step 1 Power down the library and host.
Step 2 On the rear of the library, disconnect the AC line cord and SCSI cables from the
library.
Step 3 Disconnect the network cable from the RMU.
Step 4 Remove the RMU by loosening the thumbscrew and pulling out the RMU.
Step 5 If you are not replacing this RMU, reinstall the cover plate you removed when you
initially installed the RMU.
Configuring the RMU
Once the RMU is installed, the System Administrator (SA) must set up the RMU for operation. Then
you can set the IP Address in the Scalar 24.
System Administrator Responsibilities
The System Administrator (SA) must set up the RMU for proper operation. The SA responsibilities
include establishing a network address for the RMU and establishing the Uniform Resource
Locators (URL). The network address consists of an Internet Protocol (IP) address, subnet mask,
and gateway IP Address. After the network address has been established, the SA should test the
RMU and URL via a Web browser. Once the URL has been verified and accounts have been
created, the SA can broadcast the URL address to the potential RMU users. The SA can delete
users and change any user password.
