R-Series Chassis
The ClearCube R-series chassis is a centralized chassis that houses up to eight
single-slot PC blades and up to four dual-slot PC blades. A standard 42U 19-inch rack
can hold as many as 14 chassis, for a total of 112 single-slot PC blades, 56 dual-slot
blades, or a combination of both.
Each chassis is a self-contained unit providing all of the Ethernet connections, C/Port
connections, airflow management, and power connections for PC blades. The R4300
chassis features interchangeable modules for maximum flexibility. Each chassis provides
system management connections through network and RS-485 links that you can daisy
chain from chassis to chassis. Figure 3 shows a chassis with PC blades installed.
The R4300 chassis, shown in Figure 4, provides a wide range of options for C/Port
and client connections to blades and to the ClearCube network.
The R4300 chassis provides advanced monitoring and switching functionality, with
software support for these modules provided by Sentral. The R4300 chassis and
Sentral are fully compatible with all R-series blades. The R4300 also provides full
backwards compatibility with all features implemented in Switch Manager 4.5, and is
compatible with ClearCube R4200 chassis systems utilizing Blade Switching
BackPacks (BSBPs) and Direct Connect BackPacks (DCBPs). The R4300 also
features dual redundant power supplies and dual AC power inputs.
Sentral communicates with the chassis through an Ethernet connection on the
management controller housed in each R4300. The management controller is installed
inside the R4300 and does not take up a blade slot.
