Module Placement in a Matrix E7 Chassis

Module Placement in a Matrix E7 Chassis
If you want to mix 6x1xxx, 6x2xxx, 6x3xxx, and 7H43xx‐xx series modules in the same Matrix E7
chassis, it is necessary to have a DFE bridging module such as the 7H4382‐25, 7H4382‐49,
7H4383‐49, or 7H4385‐49 installed and to also follow the module placement rules described in
"Installing Module into Matrix
to some or all modules in the chassis.

10BASE-T Network

When connecting a 10BASE‐T segment to any of the fixed front panel ports of the 7GR4202‐30,
ensure that the network meets the Ethernet network requirements of the IEEE 802.3‐2002 standard
for 10BASE‐T. Refer to the Cabling Guide for details.

100BASE-TX Network

The fixed front panel ports of the 7GR4202‐30 provide a connection that supports Category 5 UTP
cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002
100BASE‐TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. Refer to
the Cabling Guide for details.
1000BASE-T Network
The 7GR4202‐30 DFE module provides 30 ports that support 10/100/1000 Mbps via RJ45 front
panel connectors. These connections support copper wire connections that can operate up to
1000 Mbps. The device at the other end of the twisted pair segment must meet IEEE 802.3‐2002 10/
100/1000 BASE‐T network requirements for the devices to operate at Gigabit speed.

1000BASE-SX/LX Network

The optional Mini‐GBICs installed in the 7GR4270‐12 port slots 1 through 12, or in the 7GR4280‐19
front‐panel ports 1 through 18 or the optional NEM, provide fiber‐optic connections operating at
1000 Mbps (1 Gbps). Other Mini‐GBICs may support different types of cabling connections. The
device at the other end of the fiber‐optic connection must meet IEEE 802.3‐2002 Gigabit Ethernet
requirements for the devices to operate at Gigabit speed. Refer to Appendix
on Mini‐GBIC specifications.
2-2 Network Requirements
E7 or N7 Chassis" on page 3‐10 to successfully bridge data traffic
Note: If a port is to operate at 100 Mbps, Category 5 cabling must be used. Category 3 cabling
does not meet 100 Mbps specifications. For 10 Mbps operation only, Category 3 or Category 5
cabling can be used. Refer to
100BASE-TX networks and cabling.
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance between
85 and 111 ohms for 100 Mbps operation. The module is capable of operating at 10, 100, or 1000
Mbps and can automatically sense the port speed of the other device and adjust its speed
accordingly.
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance between
85 and 111 ohms for 100 and 1000 Mbps operation.
Front-panel ports 1 through 30 are capable of operating at either 10, 100, or 1000 Mbps. The
module automatically senses the speed of the other device and adjusts its speed accordingly.
