Installing Modules
One Management Module (EME) is required in each chassis. A second is
optional for redundancy. The slots for management modules are
obviously in the upper portion of the chassis due to their smaller size.
3Com recommends that you install all Management Modules prior to
adding switching modules.
This section may not apply to you if you ordered a starter kit that has the
Management Module pre-installed at the factory and if you do not intend
to install other management modules. However, read this section if you
are assembling separately ordered chassis components or if want to
install a second Management Module.
For a detailed module installation procedure, see the Enterprise
Management Engine Quick Start Guide for the CoreBuilder 9000
Enterprise Switch.
This document is available from the Switch 4007
Online Manuals CD or from the 3Com Web site.
For information on installing and operating two EMEs, see “Creating a
Redundant Configuration” next in this chapter.
Hot Insert and
Hot Swap
You do not need to turn off power to install modules in the Switch 4007
chassis. You can install modules while the chassis is operating. This action
is called a
hot insert.
You can also remove a module and install a replacement in that slot while
the chassis is operating. This action is called a
hot swap .
If your chassis is already operating in your network and you want to
remove the primary (active) Management Module and retain
uninterrupted chassis services, first ensure that a secondary (standby)
Management Module resides in the chassis. When you remove the
primary module, the secondary module activates quickly and seamlessly.
CAUTION: Do not install or remove modules during the system power-on
process or while software is downloading to any modules in the chassis.
Installing
Non-Management
Modules
For a detailed installation procedure and other module-specific
information, see the
Quick Start Guide that accompanies the module.
Guides for all modules that are supported in the Switch 4007 are
available from the Switch 4007 Online Manuals CD or from the 3Com
Web site.
