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:
GPIM—The Gigabit-Backplane Interface Module (GPIM) includes standard GPIMs that
can be installed in a single-high, single-wide GPIM slot that has gigabit connectivity to
the system backplane.
XPIM—The XPIM can be installed only in the 10-gigabit GPIM slot 3 or in the 20-gigabit
GPIM slot 6. It could be:
A single-high, single-wide LAN switch XPIM that uses one slot
A double-high, single-wide LAN switch XPIM that uses two standard slots vertically
A double-high, double-wide LAN switch XPIM 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 slot 6, which refers to the
top four slots 5 through 8.
Figure 6 on page 24 shows how the slots on the front panel of the SRX550 Services
Gateway are numbered.
