Hardware Requirements for Junos OS Release 10.3 for SRX Series Services Gateways and J Series Services Routers

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 for J Series Services Routers

The following third-party hardware is supported for use with J Series Services Routers running JUNOS software.

USB Modem

We recommend using a U.S. Robotics USB 56K V.92 Modem, model number USR 5637.

Storage Devices

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 installed and configured, it automatically acts as a secondary boot device if the primary CompactFlash card fails on startup. Depending on the size of the USB storage device, you can also configure it to receive any core files generated during a router failure. The USB device must have a storage capacity of at least 256 MB.

Table 17 lists the USB and CompactFlash card devices supported for use with the J Series Services Routers.
