SRX300 Series and SRX550 High Memory Services Gateway Interface
Overview
Mini-Physical Interface Modules (Mini-PIMs) and Gigabit-Backplane Physical Interface Modules (GPIMs)
are eld-replaceable network interface cards (NICs), which provide physical connecons to a LAN or a
WAN. You can easily insert or remove Mini-PIMs and GPIMs from the front slots of the services
gateway chassis. The Mini-PIMs and GPIMs receive incoming packets from the network and transmit
outgoing packets to the network. During this process, they perform framing and line-speed signaling for
the medium type.
The SRX300 Series Services Gateways support only Mini-PIMs. The SRX550 High Memory Services
Gateway supports both Mini-PIMs and GPIMs.

The Mini-PIMs are eld-replaceable. You can install a Mini-PIM in the Mini-PIM slot on the front panel
of the services gateway chassis.
CAUTION: The Mini-PIMs are not hot-swappable. You must power o the services
gateway before removing or installing Mini-PIMs.
SRX300 Series and SRX550 High Memory 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 SRX550 High Memory Services Gateway to provide physical connecons to a LAN
3
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 connecons for the LAN or WAN.
Interface module terminology:
GPIM—Can be installed in one of the single-high, single-wide GPIM front slots of the SRX550 High
Memory Services Gateway that have Gigabit connecvity to the system backplane.
XPIM—Can be installed only in the 10-Gigabit GPIM slot 3 or in the 20-Gigabit GPIM slot 6 on the
front panel of the SRX550 High Memory Services Gateway.
The GPIMs can have one of the following conguraons:
Single-high, single-wide LAN switch GPIM that uses one slot
Double-high, single-wide LAN switch GPIM that uses two standard slots vercally
NOTE: GPIMs are not supported on the SRX300 Series devices.
Table 2 on page 4 lists the GPIMs and XPIMs and their respecve model numbers.

Interfaces Port Naming Convenons for the SRX300 Series and SRX550
High Memory Services Gateways
When conguring a port on a Mini-Physical Interface Module (Mini-PIM) or Gigabit-Backplane Physical
Interface Module (GPIM), you must know the slot and port number assigned to the Mini-PIM or GPIM.
The slot number idenes the slot on the services gateway in which you insert the Mini-PIM or GPIM,
5
and is typically named 1, 2, 3, and so on. The port number is the port on the Mini-PIM or GPIM that is
being congured.
The name of each network interface has the following format to idenfy the physical device that
corresponds to a single physical network connector:
type-slot/pim/port
NOTE: For SRX Series Services Gateways,
pim
equals 0 for the port-naming convenon.
For the LTE Mini-PIM,
port
equals 0.
Table 3 on page 6 lists the typical interface types and interface numbers.

MTU Default and Maximum Values for Physical Interface Modules
Table 6 on page 10 denes the terms that are used in the context of maximum transmission unit
(MTU).

Table 6: MTU Terms
Term Denion
Physical Interface MTU–
Default
Default value of the MTU at the physical interface. The maximum
value of the MTU at the physical interface includes the protocol
overhead. You can congure the default MTU value at the physical
interface by using the following command:
set interface interface-name mtu mtu-value
Logical Interface MTU–Default Default value of the MTU at the logical interface. The default value
is congured at the family level and does not include the protocol
overhead. You can congure the default MTU value for each logical
unit at the logical interface by using the following command:
set interface interface-name unit interface-unit-number family
family-name mtu mtu-value
Maximum MTU Maximum MTU is the size, measured in bytes, of the largest
physical packet that a network can transmit. Any message larger
than the MTU is divided into smaller packets before it is sent to its
nal desnaon.
Table 7 on page 10 lists the MTU values for the SRX300 Series and SRX550 High Memory Services
Gateway Physical Interface Modules (PIMs).
