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.
Interface Module Terminology:
GPIM—The Gigabit-Backplane Interface Module (GPIM) includes standard GPIMs that
are 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 20-gigabit GPIM slots (slots 2 and 6 on
the front panel). It may be:
A single-high, single-wide LAN switch GPIM that uses one slot
A double-high, single-wide LAN switch GPIM that uses two standard slots vertically
A 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.
Figure 5 on page 28 shows how the slots on the front panel of the SRX650 Services
Gateway are numbered.
