J4300 and J6300 Removable Compact Flash Drive

The slot labeled
(see Figure 10) is a removable compact flash drive that accepts a type I or
II compact flash disk, as defined in the CompactFlash Specification published
by the CompactFlash Association. When the removable compact flash disk is
installed and configured, it automatically acts as the secondary boot device
if the primary compact flash drive fails on startup.
Depending on the capacity of the removable compact flash disk, you
can also configure it to receive any core files generated during a failure.
For information about configuring a removable compact flash disk, see
"Configuring Boot Devices with the CLI" on page 508.

J4300 and J6300 Physical Interface Modules (PIMs)

Physical Interface Modules (PIMs) provide the physical connection to various
network media types, receiving incoming packets from the network and
transmitting outgoing packets to the network (see Figure 11). Each PIM is equipped
with a dedicated network processor that forwards incoming data packets to the
Routing Engine, and receives outgoing data packets from the Routing Engine. During
this process, the PIM performs framing and line-speed signaling for its medium type.
