• 1000BASE-SX SFP modules provide a 1000 Mbps wired connection to a network through an
850nM (SX) fiber-optic link using an LC physical connector.
• 1000BASE-LX SFP modules provide a 1000 Mbps wired connection to a network through a
1300nM (LX/LH) fiber-optic link using an LC physical connector.
• 1000BASE-T SFP modules provide a 1000 Mbps wired connection to a network through a copper
link using an RJ-45 physical connector.
• One or Two Enhanced Security Modules. Refer to Quick Start Guide: VPN/Enhanced Security
