Transceiver Compatibility for SRX Series and J Series Devices

We strongly recommend that only transceivers provided by Juniper Networks be used
on SRX Series and J Series interface modules. Different transceiver types (long-range,
short-range, copper, and others) can be used together on multiport SFP interface modules
as long as they are provided by Juniper Networks. We cannot guarantee that the interface
module will operate correctly if third-party transceivers are used.
Please contact Juniper Networks for the correct transceiver part number for your device.

Power and Heat Dissipation Requirements for J Series PIMs

On J Series Services Routers, the system monitors the PIMs and verifies that the PIMs
fall within the power and heat dissipation capacity of the chassis. If power management
is enabled and the capacity is exceeded, the system prevents one or more of the PIMs
from becoming active.
CAUTION: Disabling power management can result in hardware damage if
you overload the chassis capacities.
You can also use CLI commands to choose which PIMs are disabled. For details about
calculating the power and heat dissipation capacity of each PIM and troubleshooting
procedures, see the J Series Services Routers Hardware Guide.

Supported Third-Party Hardware

The following third-party hardware is supported for use with J Series Services Routers
running Junos OS.
We recommend using a U.S. Robotics USB 56K V.92 Modem, model number USR 5637.
The USB slots on J Series Services Routers accept a USB storage device or USB storage
device adapter with a CompactFlash card installed, as defined in the CompactFlash
Specification published by the CompactFlash Association. When the USB device is
