Physical Interface Modules (PIMs)
Physical Interface Modules (PIMs) provide the physical connection to various network
media types. For information about individual PIMs, see “Field-Replaceable
PIMs” on page 46.
For pinouts of PIM cable connectors, see “Network Cable Specifications and Connector
Pinouts” on page 223. For PIM replacement instructions, see “Replacing a
PIM” on page 172.
The J2320 front panel has three slots and the J2350 front panel has five slots for
field-replaceable PIMs. These slots are numbered from top to bottom and from left
to right as shown in Figure 10 on page 20.
Slot 0 is a fixed interface module that contains four built-in Gigabit Ethernet ports.
For more information, see “Built-In Gigabit Ethernet Ports” on page 23.
