Mini-Physical Interface Modules (Mini-PIMs) and Gigabit-Backplane Physical Interface
Modules (GPIMs) are field-replaceable network interface cards (NICs) supported on the
Juniper Networks SRX Series Services Gateway for the branch. You can easily insert or
remove Mini-PIMs and GPIMs from the front slots of the SRX Series Services Gateway
chassis. The Mini-PIMs and GPIMs provide physical connections to a LAN or a WAN. 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 SRX Series Services Gateways run Junos OS.

CAUTION:

The Mini-PIMs available on the SRX Series Services Gateway are

not hot-swappable. You must power off the device before removing or
installing Mini-PIMs.

NOTE:

Only SRX650 Services Gateway supports hot-swappable functionality

for GPIMs.
