SRX550 HM Interface Modules

SRX550 High Memory 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 1 shows how the slots on the front panel of the SRX550 Services Gateway are numbered.

CAUTION:

SRX550 Services Gateway does not support hot-swappable functionality for GPIMs.

For more information about supported GPIMs and the minimum supported Junos OS release, see SRX Series Services Gateway Interface Modules and Compatibility

For details about the supported GPIMs and XPIMs, see the SRX Series Services Gateways for the Branch Physical Interface Modules Hardware Guide.

Figure 2, Figure 3, and Figure 4 show the three form factors for the services gateway GPIMs.

Figure 4: Example of a Double-High, Double-Wide XPIMExample of a Double-High, Double-Wide XPIM

Because the services gateway GPIMs communicate with the backplane at various performance levels, you must install them in the correct slots.

Note:

Remove the GPIM adapter before you install double-high, double-wide XPIM.

SRX550 High Memory Services Gateway Mini-Physical Interface Modules

The SRX550 High Memory Services Gateway has two slots (slots 1 and 2) for installing Mini-Physical Interface Modules (Mini-PIMs).

A Mini-PIM is a network interface card that is installed in the services gateway to provide physical connections to a LAN or WAN. The Mini-PIMs supported on the services gateway are field-replaceable units (FRUs); which you can remove or replace at your site. You can install Mini-PIMs into the two Mini-PIM slots on the front panel of the services gateway chassis.

The SRX550 High Memory Services Gateway supports the following Mini-PIMs:

  • 1-Port Serial Mini-Physical Interface Module (SRX-MP-1SERIAL-R)

  • 1-Port T1/E1 Mini-Physical Interface Module (SRX-MP-1T1E1-R)

  • 1-Port VDSL2 (Annex A) Mini-Physical Interface Module (SRX-MP-1VDSL2-R)

  • LTE Mini-Physical Interface Module (SRX-MP-LTE-AE and SRX-MP-LTE-AA)

  • Wi-Fi Mini-Physical Interface Module (SRX-MP-WLAN-US, SRX-MP-WLAN-IL, and SRX-MP-WLAN-WW)

For more information on the Mini-PIMs, see the SRX300 Series and SRX550 High Memory Gateway Interface Modules Reference.
