SRX Series Services Gateway Gigabit-Backplane Physical Interface Modules Overview
A Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in the front slots of the 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.
Interface module terminology:
- GPIM—The Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in a single-high, single-wide GPIM front slot of the SRX650 Services Gateway that has gigabit connectivity to the system backplane.
- XPIM—The XPIM (10 Gigabit Ethernet GPIM) can be
installed only in the 20-gigabit GPIM slots (slots 2 and 6 on the
front panel). It can have one of the following configurations:
- Single-high, single-wide LAN switch GPIM that uses one slot
- Double-high, single-wide LAN switch GPIM that uses two standard slots vertically
- Double-high, double-wide LAN switch GPIM that uses two standard slots vertically and two standard slots horizontally
Note: When installing the 24-Port Gigabit Ethernet XPIM, which uses four slots, you must install it in the 20-gigabit GPIM slots 2 and 6, which refer, to the bottom four slots 1 to 4, or the top four slots 5 to 8.
Table 1 lists the GPIMs and XPIMs and their model numbers.

Quad CT1/E1 GPIM | SRX-GP-QUAD-T1-E1 |
2-Port 10 Gigabit Ethernet XPIM | SRX-GP-2XE-SFPP-TX |
16-Port Gigabit Ethernet XPIM | SRX-GP-16GE |
24-Port Gigabit Ethernet XPIM | SRX-GP-24GE |
Figure 1 shows how the slots on the front panel of the SRX650 Services Gateway are numbered.

| Note: GPIMs/XPIMs are Online Insertion and Removal capable. Because the services gateway GPIMs communicate with the backplane at various performance levels, you must install them in the correct slots. |
Figure 2, Figure 3, and Figure 4 show the three form factors for the services gateway GPIMs.
