DFE Module Placement and Installation Rules
3-4 Installation
Figure 3-1 Examples, Slot Numbers/Module Placement in Matrix E7 Chassis
To ensure proper operation of the system, consider the following examples and rules for
module placement in either chassis.
Example 1 ( Figure 3-1 , A)
Shows one module installed in the chassis. If the chassis is populated with only one
4xxxxx, it must be installed in slot 1.
Rule: If only one 4xxxxx is installed in the chassis, it must be in slot 1. Always install a
4xxxxx in slot 1 of the chassis.
Example 2 ( Figure 3-1 , B)
Shows the chassis fully populated with 4xxxxx modules. All modules may be hot
swapped, except the module in slot 1. If the module in slot 2 is designated as a redundant
management module, the module in slot 1 may be hot swapped without shutting down
the system. The module in slot 2 can be designated using the CLI command
set license <license key>.
For information on how to use this command, refer to the Enterasys Matrix DFE‐Gold Series
Configuration Guide. To access this guide on the web, refer to
“Related Documents” on
page xvi.
Without a designated redundant management module in slot 2, removing the module in
slot 1 will shut down the system.
Rule: Any module in a 4xxxxx system, including the management module in slot 1, may
be hot swapped when there is a 4xxxxx module designated as a redundant management
module in slot 2.
