Installing the 9Cx14 Chassis
This document contains information necessary to install the SmartSwitch 9000
9C114 and 9C714 chassis. It is designed for the initial installation only. For
detailed operational information on the various SmartSwitch 9000 components,
refer to the following manuals:
Chapter 1
SmartSwitch 9000 9C300-1 Environmental Module User’s Guide
SmartSwitch 9000 9C214-1 AC Power Supply Installation Guide
SmartSwitch 9000 9C214-2 DC Power Supply Installation Guide
Local Management User’s Guide
In addition, each interface module has a user’s guide.
The SmartSwitch 9000
The SmartSwitch 9000 chassis is a networking platform that provides support for
the configuration and operation of up to 14 Cabletron Systems SmartSwitch 9000
interface modules.
Features
Multiple Tec hnology Support
The design of the chassis allows it to provide support for existing and future
Local Area Networking technologies such as Ethernet, Fast Ethernet, Gigabit
Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), Systems Network
Architecture (SNA), Wide Area Networks (WAN), and Asynchronous Transfer
Mode (ATM).
1-1
Installing the 9Cx14 Chassis
Redundant Power Supply Modules
The 9C114 and 9C714 support the installation of two power supplies for power
supply redundancy and load sharing. If a 9C500 Power Box is used, up to six
power supplies may be installed.
9C300-1 Environmental Module
The 9C300-1 Environmental Module provides out-of-band management
capabilities, monitors power supply and environmental status, and has a built-in
cooling system. The 9C300-1 Environmental Module is also “hot swappable” so
that it can be removed for repair or replacement without causing network
downtime. For details refer to the
User’s Guide
.
SmartSwitch 9000 9C300-1 Environmental Module
The Backplane
The 9C114 SmartSwitch 9000 pr ovides six distinct backplane buses, and the 9C714
provides an additional seventh bus, the Cell Transfer Matrix. Each bus serves a
particular set of needs. The seven backplane buses are shown in Figure 1-1.

Figure 1-1. The SmartSwitch 9000 Backplane Buses
Installing the 9Cx14 Chassis
The descriptions of the seven backplane buses are as follows:
System Management Bus 1
The System Management Bus 1, abbreviated SMB-1, is a management bus
devoted solely to transferring management information between the modules in
the chassis. It is through the SMB-1 that modules inform each other, and the
Environmental Module, of their current operating status, diagnostic test results,
initialization queries and other information. The SMB-1 operates at 1 Mbps, and
every module in the chassis has a connection to it.
System Management Bus 10
The System Management Bus 10, or SMB-10, performs similar functions to those
of the SMB-1 previously discussed in this section. The SMB-10 bus is devoted to
the transfer of management data within the chassis, but is used for out-of-band or
Local Management operations. The SMB-10 operates at Ethernet speeds of
10 Mbps, and is connected to any manageable module in the chassis. Access to the
SMB-10 for Local Management operations is provided through an Ethernet Port
Interface Module (EPIM) slot on the 9C300 Environmental Module, or through
the serial COM ports, also located on the Environmental Module. The SMB-10 can
also be accessed from in-band management through a Telnet application.
The Flexible Network Buses
The Flexible Network Buses, FNB-1 and FNB-2, are the primary backplane buses
used to connect SmartSwitch 9000 modules for shared network designs. Each
FNB bus operates as a dual, counterrotating Fiber Distributed Data Interface
(FDDI) ring. Each FNB bus operates at 100 Mbps, and consists of one primary ring
and its associated secondary ring. In the event of a failure of a station or a
connection, the signals from the primary ring are wrapped onto the secondary
ring, creating a single ring and allowing network traffic to continue circulating.
The construction of the FNB backplanes includes shunting connectors which
allow network signals to pass by unpopulated slots in the chassis. This design
frees Network Managers from a dependence on specific ordering or placement of
modules, and allows modules to be removed from the FNB without causing a
wrap of the FDDI ring.
The Internal Network Buses
The Internal Network Buses, abbreviated INB-1 and INB-2, are designed to
simultaneously support both packet and ATM cell transport. Each INB data
channel is 64 bits wide (56 byte data bus and 8 byte management and control bus)
and runs at a clock rate of 40 mhz, yielding a sustained data rate of 2 Gbps, and a
burst rate of 2.5 Gbps. The 8 byte management and control bus allows all
signaling and bus arbitration functions to occur out-of-band with regard to user
data.
1-3
Installing the 9Cx14 Chassis
The Cell Transfer Matrix (installed in the 9C714 chassis only)
The Cell Transfer Matrix provides a Time Division Multiplexed (TDM) based
mesh of full duplex, high speed (1.6 Gbps) dedicated interconnections capable of
carrying standard ATM cell traffic. These interconnections are a series of point-topoint links between an individual module, and every other module that directly
connects to the Cell Transfer Matrix. If the 9C714 chassis has 14 modules that
connect to the CTM installed, there are 182 point-to-point links between all the
modules, providing a total aggregrate switching capacity of 75 Gbps.

Site Guidelines
The following guidelines must be followed to select a suitable site for the
SmartSwitch 9000. If not, unsatisfactory network performance may result.
The site must have an unrestricted free surface area ar ound the SmartSwitch 9000
chassis, allowing for free movement of air. An open space of at least 84 high by
63.5 wide by 81.24 centimeters deep (33 high by 25 wide by 32 inches deep) is the
minimum recommended. If the unit is installed in an enclosed equipment cabinet,
the cabinet should have a built-in cooling fan.The maximum theoretical heat
dissipation of the SmartSwitch 9000 is 8700 BTUs per hour. Actual heat
dissipation will vary depending on the modules installed in the SmartSwitch 9000
chassis. The temperature of the location must be maintained between 5° and 40°C
(40° and 104°F). Changes in temperature greater than 10°C (18°F) per hour should
not occur.
Installing the 9Cx14 Chassis
A standard 3-prong power receptacle must be located within 6 feet of the system.
One circuit is recommended for each power supply. The AC wiring for the
receptacle must be able to supply 12 amps at 120 volts or 6 amps at 220 volts.
