card come standard with 256 MB of memory. J4350 routers can contain
between 256 MB and 2 GB of memory. For instructions on adding memory,
see “Removing and Installing DRAM Modules” on page 155.
Each J4350 chassis contains four built-in Gigabit Ethernet ports with link
speeds of 10/100/1000 Mbps over a copper interface, and six slots for
field-replaceable Physical Interface Modules (PIMs). Two of the six slots
(slots 3 and 6) support high-speed interfaces (ePIMs).
The J4350 Services Router supports the following field-replaceable
Physical Interface Modules (PIMs):
SFP Gigabit Ethernet ePIM (1 port)
