SRX550 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 complement the onboard Ethernet interfaces to extend the types and port counts of network connections for the LAN or WAN.

Interface Module Terminology:

Figure 9 shows how the slots on the front panel of the SRX550 Services Gateway are numbered.

Caution: SRX550 Services Gateway does not support hot-swappable functionality for GPIMs.

For more information about supported GPIMs and the minimum supported Junos OS release, see SRX Series Services Gateway Interfaces Models and Compatibility

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

Figure 10, Figure 11, and Figure 12 show the three form factors for the services gateway GPIMs.

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

Note: Remove the GPIM adapter before you install double-high, double-wide XPIM.
