ItemSpecification

B2G124-48

RJ45 ports 1 through 48 Forty-eight, 10BASE-T/100BASE-TX/1000BASE-T compliant ports with auto-sensing and auto-negotiation through the RJ45 connections.

SFP ports 45 through 48 Four slots that support optional Mini-GBICs for 1000BASE-FX fiber-optic connections and 1000BASE-T copper connections.

When an SFP transceiver (Mini-GBIC) is installed in ports 45 through 48 and establishes a link, the associated fixed front panel RJ45 10BASE-T/100BASE-TX /1000BASE-T port is disabled.

B2H124-48

RJ45 ports 1 through 48

SFP ports 49 through 52

Forty-eight, 10BASE-T/100BASE-TX compliant ports with auto- sensing and auto-negotiation via RJ45 connectors.

Four slots that support optional Mini-GBICs for 1000BASE-T Gigabit copper and 1000BASE-FX fiber-optic connections. Unlike the B2G124-24 and B2G124-48, all ports may be linked and operating without affecting any RJ45 ports.
