Specifications

Examples throughout both of these guides describe how to configure screen
options using the [set security screen screen-name] CLI statements. Instead, you
should use the [set security screen ids-option screen-name] CLI statements. All
screen configuration options are located in the [set security screen ids-option
screen-name] level of the configuration hierarchy.
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 software with enhanced services.
USB Modem We recommend using a Multi-Tech MultiModem MT5634ZBA-USB-V92 USB modem
with J-series Services Routers.
Storage Devices The USB slots on J-series Services Routers accept a USB storage device or USB storage
device adapter with a compact flash disk 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 compact flash disk 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 1 on page 9 lists the USB and compact flash storage devices supported for
use with the J-series Services Routers.
