Configuring the RMC

The following steps outline the process required to set up and configure your choice of
chassis control computer/server. These steps also explain the setup of the
communication link to the chassis. This description assumes that you are choosing to
control your chassis with an RMC, rather than with the recommended RMM.
• Select your chassis control computer/server: For browser-based control you can
use a PC blade or a third-party box PC, server, or a notebook computer that has an
Ethernet connection. This computer/server does not need to be dedicated solely to
this function – it can also be used for other tasks depending on the application.
• Connect your control computer to the network: Your control computer must be
on the same LAN that connects to the Ethernet control port of the Primary chassis
with the RMC installed.
• Connect the Primary chassis and RMC to the network: An RMC can be
installed in either a BSBP or a DCBP. If an RMC is installed in a Control Chain that
contains R4300 chassis with RMMs, the Primary chassis is always the one that
has the RMC installed. The Primary chassis is indicated by a LED on the back of
the chassis next to the control in/out ports that are colored green. When the ENET
indicator is lit, this means that an RMC card is installed and this is a Primary
chassis. If the RS-485 indicator is lit, it means that this is a Slave chassis. If you
have more than one rack of chassis, you will have multiple Primary chassis,
typically one per rack.
• Daisy-chain multiple chassis: If your installation has multiple chassis, then
daisy-chain the RS-485 control connections with C/Port cables. A green cable is
provided with the chassis. Connect the RS-485 Control Output from the first
BackPack to the RS-485 Control Input on the next BackPack/chassis. Continue
daisy-chaining until all chassis are connected. You can connect all 14 chassis in a
rack together in this way. Additional chassis require an RMC for each rack of
chassis.
• Configure the Blade Switching BackPack for Various Modes: Configuration of
your Blade Switching BackPack depends on that modes of operation you will use.
All modes can be used together, or individual modes can be used alone.
• Spare Switching Configuration: Multiple spare PC blades can be configured per
chassis. At the other extreme, one spare can be made available to support 14
chassis. A Spare blade is configured by connecting a short C/Port cable from its
C/Port connection to the SPARE IN connection on the chassis. For one spare to
support multiple chassis the SPARE OUT connector is daisy-chained to the
SPARE IN connector on the next chassis and so on. A short red cable for Spare
daisy-chaining is included with your chassis.
• Administrator Switching Configuration: For onsite control, the IT administrator
can connect a separate C/Port directly to the chassis' administrator C/Port input.
This console is separate from the computer that is used to control the chassis. For
administering PC blades in more than one chassis, the Administrator C/Port
Output connection can be daisy-chained to the Administrator C/Port Input
connection on the next chassis and so on (as many as 14 chassis can be linked).
A short yellow cable for Administrator C/Port daisy-chaining is included with your
chassis.
• Supervisor Switching Configuration: This feature is configured in the same
way as the Administrator mode.
• 8 x 8 Switching: This capability lets as many as eight C/Ports switch between
any eight blades in a single chassis. This capability also lets one or more users
share multiple blades dynamically. Control over the 8 x 8 matrix of connections is
