16-Port Gigabit Ethernet XPIM (PoE) Overview

The 16-Port Gigabit Ethernet XPIM is a double-high, single-wide LAN switch Gigabit-Backplane Physical
Interface Module (GPIM) that uses two standard slots vertically. It is available with or without Power over
Ethernet (PoE) support. The SRX550 High Memory Services Gateway supports the PoE model. The PoE
GPIMs provide ports that supply electric power over the same ports that are used to connect network
devices. For more information about PoE, see
Services Gateway Interfaces" on page
The 16-Port Gigabit Ethernet XPIM must be installed in one of the following 20-Gigabit slots on the
SRX550 High Memory Services Gateway:
Slot 3
Slot 6
NOTE: The 16-Port Gigabit Ethernet XPIM is supported on both slot 3 and slot 6 of the SRX550
High Memory Services Gateway. However, the performance (bandwidth) in slot 3 will be limited
as it has a 10G back link.
NOTE: The SRX550 High Memory Services Gateway does not support hot-swappable
functionality for GPIMs.
