How OS Network Connections Are Mapped to NICs on
Chassis Backpack
After you insert a blade in a chassis, your Windows operating system shows 2 network
connections in the Network Connections window (click Start > Control Panel and
then double-click Network Connections to display connections). The following table
shows how each network connection that your OS displays is mapped to the Ethernet
ports (Primary & Secondary) on the rear of the chassis (shown Figure 27 on page 40).
C/Port Cabling
When connecting a C/Port to an R3080D, use the C/Port connector on the Connect
Bay Module that corresponds to the slot that the blade is in (the Connect Bay Module
is located on the rear of the chassis on the far left side, as shown in Table 4 on
page 28). For example, if an R3080D is in chassis slot 3, connect your C/Port cable to
C/Port connector 3.
RMM Firmware Update Procedures
To update RMM firmware, you need to have a TFTP server configured on your
network. The firmware can be installed using Telnet or using Sentral. You need to
first install the firmware on the Primary RMM of each Chassis Group, and then
propagate the firmware update to the rest of the RMMs in the group.
Although downgrading a firmware version is possible with the RMM architecture, it is
never recommended.
Updating RMM Firmware Using Telnet
To install an RMM firmware update using telnet, do the following:
1. Download the firmware update package from the ClearCube Support Web site.
2. Unzip the package, and copy the files to the directory where the TFTP server is
configured to get the file.

NOTE
Do not remove any R4300 modules when updating the RMM
firmware. This can cause the firmware to become corrupted.
The HEALTH LED on the RMM displays an amber signal when
firmware is being updated.
