Table 7 Interface Attributes of the SIC-1GEC

Attribute Description

Connector RJ-45

Interface type MDI

Frame format

• Ethernet_II

• Ethernet_SNAP

• IEEE 802.2

• IEEE 802.3

Operation mode

10/100/1000 Mbps autosensing

Full/half duplex

NOTE:

SIC-1GEC uses COMBO interface; it cannot support fiber and electrical interfaces at the same time. When

the router is powered on, the electrical interface takes effect by default. To use a fiber interface, confi

ure

it at the command line interface (CLI).
