Connectivity
1-6 Introduction
Network Expansion Module Option
The 7H4382-49 and 7H4383-49 option slots provide access to an installed network expansion
module (NEM). Refer to the Enterasys Networks web site for a current listing of the available
NEMs. Specific installation instructions are shipped with each NEM.
1.3 CONNECTIVITY
7H4382-49
Depending on how the 7H4382-49 DFE module ( Figure 1-1 ) is configured, it can support up to:
•
48, 10BASE-T/100BASE-TX switched ports connected through 48 fixed front panel
connectors, and the bridge function between FTM1 and FTM2 connections on the chassis
backplane. This enables bridging between 6x1xxx, 6x2xxx, 6x3xxx, and 7x4xxx series modules
installed in the same Matrix E7 chassis, or
•
48, 10BASE-T/100BASE-TX switched ports and an optional network expansion module.
7H4383-49
Depending on how the 7H4383-49 DFE module ( Figure 1-1 ) is configured, it can support up to:
•
48, 10BASE-T/100BASE-TX switched ports connected through four fixed RJ21 front panel
connectors, and the bridge function between FTM1 and FTM2 connections on the chassis
backplane. This enables bridging between 6x1xxx, 6x2xxx, 6x3xxx, and 7x4xxx series modules
installed in the same Matrix E7 chassis, or
•
48, 10BASE-T/100BASE-TX switched ports and an optional network expansion module.
Note: The 7H4382-49 does not support both the FTM bridge function and an optional
NEM at the same time. With an optional NEM installed, the FTM bridging function is
disabled. All ports remain active in either case.
Note: The 7H4383-49 does not support both the FTM bridge function and an optional
NEM at the same time. With an optional NEM installed, the FTM bridging function is
disabled. All ports remain active in either case.
