Key Features:
- 8 x 10/100Base-TX LAN Ports: Eight standard Ethernet ports supporting speeds of 10 Mbps and 100 Mbps using RJ45 connectors.
- 8 x 100Base-FX LAN Ports: Eight fiber optic Fast Ethernet ports using FX transceivers and likely LC connectors. These support a speed of 100 Mbps.
- 2 x SFP (Mini-GBIC) Ports: Two Small Form-factor Pluggable ports that can accept Gigabit Ethernet or other types of SFP transceivers for flexible uplink or stacking options. These ports support speeds of 1 Gbps.
- Stackable: Supports stacking with other Enterasys SecureStack A2 series switches to increase port density and overall capacity.
- Layer 2 Management: Offers Layer 2 management features for VLANs, QoS, and traffic management.
