SRX300 Series and SRX550M Interface Modules Support

Mini-Physical Interface Modules (Mini-PIMs) and Gigabit-Backplane Physical Interface Modules (GPIMs) are field-replaceable network interface cards (NICs), which provide physical connections 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.

Table 1 lists the supported Mini-PIMs and their model numbers.

The Mini-PIMs are field-replaceable. You can install a Mini-PIM in the Mini-PIM slot on the front panel of the services gateway chassis.

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 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—Can be installed in one of the single-high, single-wide GPIM front slots of the SRX550 High Memory Services Gateway that have Gigabit connectivity 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 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

  Note:

  GPIMs are not supported on the SRX300 Series devices.

Table 2 lists the GPIMs and XPIMs and their respective model numbers.

Figure 1 shows how the slots on the front panel of the SRX550 High Memory Services Gateway are numbered. Slots 1 and 2 are for Mini-PIMs, and slots 3 through 8 are for GPIMs.

Figure 2 and Figure 3 show the form factors for the services gateway GPIMs.

When configuring 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 identifies the slot on the services gateway in which you insert the Mini-PIM or GPIM, 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 configured.

The name of each network interface has the following format to identify the physical device that corresponds to a single physical network connector:

type-slot/pim/port

Table 3 lists the typical interface types and interface numbers.

Table 4 shows the types of Mini-Physical Interface Modules (Mini-PIMs) with the SRX Series devices and the Junos OS releases that support them.

Table 5 shows the type of Gigabit-Backplane Physical Interface Modules (XPIMs), along with the SRX Series devices and the Junos OS releases that support them.

Table 6 defines the terms that are used in the context of maximum transmission unit (MTU).

Table 7 lists the MTU values for the SRX300 Series and SRX550 High Memory Services Gateway Physical Interface Modules (PIMs).

Table 8 lists maximum transmission unit (MTU) values for VDSL- Mini-PIM AT mode (Encapsulation).

Power over Ethernet (PoE) supports the implementation of the IEEE 802.3 af and IEEE 802.3 at standards, which allow both data and electric power to pass over a copper Ethernet LAN cable.

The PoE ports supply electric power over the same ports that are used for connecting network devices. PoE ports allow you to plug in devices that require both network connectivity and electric power, such as voice over IP (VoIP), IP phones, and wireless access points.

The PoE ports for the SRX550 High Memory Services Gateway reside on the individual XPIMs. The SRX550 High Memory Services Gateway supports the 16-Port Gigabit Ethernet XPIM with PoE.

The active Services and Routing Engine manages the overall system PoE power. You can configure the services gateway to act as power sourcing equipment to supply the power to the GPIMs connected on the designated PoE ports.

Table 9 lists the PoE specifications for the SRX550 High Memory Services Gateway.

Table 10 shows the power consumption values of each Physical Interface Module (PIM).
