Gigabit Interface Converters (GBICs)
The OS7-GNI-U2 module provides two Gigabit Interface
Converters (GBIC) slots. A GBIC is a Gigabit Ethernet port
module that is hot-pluggable—i.e., it can be installed or
removed while the GNI is powered on and operating without
the risk of damage to the GBIC module or the host circuitry.

module that is hot-pluggable—i.e., it can be installed or
removed while the GNI is powered on and operating without
the risk of damage to the GBIC module or the host circuitry.
When a GBIC is installed, the switch automatically gathers
basic GBIC information via the connector’s serial E2PROM
interface. This information includes the GBIC’s capabilities,
standard interfaces, manufacturer, and other information.
