Introduction
This chapter introduces the 6H302-48 and 6H303-48 Fast Ethernet modules.
The 6H302-48 module ( Figure 1-1 ) features 48 10BASE-T/100BASE-TX switched ports
connected through 48 RJ45 front panel connectors.
The 6H303-48 module ( Figure 1-1 ) features 48 10BASE-T/100BASE-TX switched ports
connected through 4 RJ21 front panel connectors.
Each of the fixed front panel ports can operate in either half-duplex or full-duplex mode of
operation, as determined by auto-negotiation. Full-duplex can also be manually configured.
Each high-speed network switching module supports IEEE 802.1D switching (bridging).
Distributed Chassis Management (DCM) and SecureFast Switching (SFS) functionality is not
supported when the modules are installed in the Matrix E7. Distributed Chassis Management and
SecureFast Switching functionality is supported when the modules are installed in the 6C105
SmartSwitch 6000 chassis.
The module ports can be configured to control traffic in several ways, including prioritizing traffic
flow according to protocol type. The module can also be configured to establish 802.1Q Virtual
Local Area Networks (VLANs) and control the flow of frames associated with each VLAN
according to priority and Ether type. Detailed information about VLANs is provided in the
Matrix E7 Series and SmartSwitch 6000 Series Local Management User’s Guide.
The module receives power and backplane connectivity when it is inserted into a Matrix E7 or a
6C105 SmartSwitch 6000 chassis.
Important Notice
Depending on the firmware version used in the module, some features described in this document
may not be supported. Refer to the Release Notes shipped with the module to determine which
features are supported.
There are restrictions on the version of firmware required for 6H302-48 modules with a serial
number starting with 3655xxxxxx. The serial number is visible on the top ejector tab of the switch,
or by querying the PIC MIB. For firmware in the 5.x track, version 5.03.05 or higher must be used
on 6H302-48 modules with a serial number starting with 3655. For the 4.x firmware track, 4.08.41
or higher must be used on 6H302-48 modules with a serial number starting with 3655.
