Juniper SRX-GP-16GE. Ethernet interface type: Gigabit Ethernet, Ethernet LAN data rates: 10,100,1000 Mbit/s, Copper ethernet cabling technology: 1000BASE-T, 100BASE-TX, 10BASE-T. Compatibility: SRX650A Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in the front slots of the SRX550 or SRX650 Services Gateway to provide physical connections to a LAN or a WAN. The GPIM receives incoming packets from a network and transmits outgoing packets to a network. These modules will complement the onboard Ethernet interfaces to extend the types and port counts of network connections for the LAN or WAN.
