Interface speed and duplex mode
10 Mbps
Full/half duplex, auto-negotiation
100 Mbps
Full/half duplex, auto-negotiation
1000 Mbps
Full duplex
NOTE:
•
When 10/100 Mbps and half duplex/full duplex are specified for an Ethernet copper port, the Ethernet
copper port operates in forced mode. When 1000 Mbps is specified or the interface speed and the
duplex mode are not simultaneously specified for an Ethernet copper port, the port operates in
auto-negotiation mode.
•
When operating in forced mode, an Ethernet copper port does not support auto MDI/MDI-X.
•
When operating in auto-negotiation mode, an Ethernet copper port supports auto MDI/MDI-X.
Interface cables
The HIM-4GBE/HIM-8GBE uses a category-5 straight-through or crossover Ethernet cable when
operating at 10/100 Mbps, and uses a category-6 cable (recommended) when operating at 1000
Mbps. For the appearance and connection of a HIM-4GBE/HIM-8GBE interface cable, see

Connecting an Ethernet interface cable
HIM-4GBP (RT-HIM-4GBP-H3)/HIM-8GBP (RT-HIM-8GBP-H3)
The HIM-4GBP and HIM-8GBP are high-speed Layer 3 GE interface modules. A HIM-4GBP provides 4,
and a HIM-8GBP provides 8 Small Form-Factor Pluggable (SFP) ports that support Layer 3 routing. Each
port is provided with a bi-color LED, which indicates the running status of the port. Connected to the
processor through an SPI-4 high-speed bus, the HIM-4GBP or HIM-8GBP provides a full range of
high-performance functions of Layer 3 Ethernet interfaces.
