2-10 Riverstone Networks RS 32000 Switch Router Getting Started Guide

Hardware Overview Introduction

You can install line cards in any order in the slots. For example, you could install line cards in slots 2 and 5 and leave

the other line card slots empty. The RS provides non-blocking throughput regardless of the software features you are

using. Therefore, you do not need to “load balance” line cards by placing them in certain physical relationships to

balance the load on the backplane. Regardless of where you install the line cards, the backplane can provide full,

non-blocking throughput.

2.4.2 Backplane

The backplane occupies the rear of the chassis and connects the power supplies, Control Modules, and line cards

together. The power supplies use the backplane to provide power to the system. The line cards and Control Modules

use the backplane to exchange control information and packets. The backplane is installed at the factory.

2.4.3 Fan Assembly

The RS 32000 contains a fan assembly to provide a cooling air flow across the Control Module(s) and line cards. The

fan assembly is located below the vertical slots. The RS 32000 fan assembly contains six fans. The fan assembly is

hot-swappable and you can replace the assembly yourself, if necessary.

Warning For safety, if you are hot swapping out the fan assembly, pull the assembly out

one-inch and allow the fans to stop rotating before pulling it all the way out.

To prevent system damage, the RS should be run for no longer than 15

minutes without replacing the fan assembly.

Note To ensure that the fan assembly can provide adequate cooling, always provide a

minimum of 3 inches of clearance above and behind the chassis.
