Hardware Requirements for JUNOS Release 10.1 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 so on) 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.
We recommend using a U.S. Robotics USB 56K V.92 Modem, model number USR
USB Modem
5637.
The USB slots on J Series Services Routers accept a USB storage device or USB storage
Storage Devices
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 7 on page 172 lists the USB and CompactFlash card devices supported for use
with the J Series Services Routers.
