Requirements and
Options
The Switch 4007 chassis provides the following features:
■
Bays for two power supplies to provide from 820 watts to 1860 watts,
depending on the type and quantity of installed modules.
■
Power fault-tolerant mode so that you can reserve the power of a
single power supply to act as backup if one of the power supplies fails.
■
Four exhaust fans (in one fan tray) to make sure that the chassis
maintains the optimal temperature for operation.
■
Two management module slots that do not take up space for switch
fabric modules or interface modules (there are seven other slots for
these types of modules).
■
One switch fabric module slot (leaving six slots for LAN interface
modules).
Requirements Building a functional Switch 4007 requires the following items:
■
One Switch 4007 chassis
■
A sufficient number of power supplies to support all installed
components
■
A sufficient number of cooling fans to support all installed
components
■
One Management Module
The Management Module may be referred to as the Enterprise
Management Engine (EME) in this guide or in the product’s management
interfaces. This is because the heritage of the Switch 4007 product line is
the CoreBuilder
®
9000 product line.
■
One Gigabit Ethernet (GEN) Switch Fabric Module (select a 24-port
module or 9-port module)
■
One or more interface modules that connect to your LAN. Examples:
■
36-port 10/100BASE-TX Fast Ethernet Layer 2 Switching Module
■
9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module
■
4-port GBIC Gigabit Ethernet Multilayer Switching Module
Multilayer Switching Modules may be referred to as Layer 3 Switching
Modules either in this guide or in the product’s management interfaces.
This is because the heritage of the Switch 4007 product line is the
CoreBuilder
