The chassis uses standard network cables with RJ45 connectors to connect to
C/Ports and to an Ethernet network. These can be CAT5, CAT5e, CAT6, or CAT6e
cables. C/Ports require straight-through cables with all four twisted pairs available.
Network connections follow standard Ethernet guidelines. In practice, identical copper
media can be used for C/Ports and for network connections, although ClearCube
recommends using different cable colors for C/Port and network connections to
simplify installation and maintenance. Throughout this guide, "C/Port cable" and
"network cable" refer interchangeably to copper-media cable such as CAT5, CAT5e,
CAT6, or CAT6e.
Each fully loaded chassis requires eight C/Port cables with RJ-45 connectors for
connections to C/Ports at the desktop and eight network cables for blade connections to
the Ethernet network hub or switch. Additionally, short color-coded C/Port cables (Green
for RS485, Red for Sparing, and Yellow for Admin Port) are provided to configure and
daisy-chain your BackPacks. You need eight network cables per chassis to connect the
blades to your network switch. If using blades with dual network ports and a 16-port
Ethernet module in an R4300, you need 16 Ethernet cables per chassis. For I/Port-only
installations, you will not need to connect any cables to the C/Port connections. With
I/Ports, the cables going to the desktop are connected directly to your network switch.
NOTE: The C/Port cable connections use all four-wire pairs for the connection from the
PC blade to the C/Port. If your installation currently splits out wire pairs for
multiple uses, you must ensure that a separate full connection is available for
each blade to C/Port connection.
Figure 11, Figure 12, and Figure 13 provide schematics of the cabling required to
connect your chassis to User Ports and your Ethernet network.
