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:
•
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 25 shows how the slots on the front panel of the SRX550 Services Gateway are numbered.
