SRX650 Services Gateway Gigabit-Backplane Physical Interface Modules

A Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in the front slots of the 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.

Caution: GPIMs are hot-swappable.

For more details about the supported GPIMs and XPIMs, see the SRX Series Services Gateway for the Branch Physical Interface Modules Hardware Guide.

Figure 8, Figure 9, and Figure 10 show the three form factors for the services gateway GPIMs.

Since the services gateway GPIMs communicate with the backplane at various performance levels, you must install them in the correct slots.
