B3G124-48P Stackable Switch

The B3G124‐48P (Figure 1‐2) has several types of front panel port connections, which include:

•Forty‐eight RJ45 ports (10/100/1000 Mbps, 1000BASE‐T copper ports) that also support PoE for connections to network 803.2af compliant PDs (powered devices).

•Four SFP slots for optional Small Form Pluggable (SFP) Mini‐GBICs for 1000BASE‐SX/ LX fiber‐optic connections and 1000BASE‐T copper connections.

Note: The Mini-GBIC ports cannot be active simultaneously with their corresponding 10/100/1000BASE-T ports. For example, if SFP port 48 establishes a link first on the B3G124-48P, the 10/100/1000BASE-T built-in RJ45 port 48 is not available and vice-versa.

•Rear panel connectors for high‐speed connections in a stack configuration.

•Rear panel Redundant Power Supply connector used to connect to a SecureStack PoE Redundant Power Supply (C2RPS‐POE). The switch connects to the C2RPS‐POE using a C2RPS‐POE cable.
