Physical Interface Modules (PIMs) provide the physical connection to various network media types. For information about individual PIMs, see Field-Replaceable PIMs.
For pinouts of PIM cable connectors, see Network Cable Specifications and Connector Pinouts. For PIM replacement instructions, see Replacing a PIM.
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.
Slot 0 is a fixed interface module that contains four built-in Gigabit Ethernet ports. For more information, see Built-In Gigabit Ethernet Ports.
