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 38.
For pinouts of PIM cable connectors, see “Network Cable Specifications and Connector
Pinouts” on page 179. For PIM replacement instructions, see “Replacing a
PIM” on page 120.
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 14.
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 17.

Power Button and POWER LED
The power button is located on the left side of the front panel (see
Figure 1 on page 8). You can use the power button to power the Services Router
on and off. When you power on the router, the Routing Engine boots as the power
supply completes its startup sequence.
The POWER LED is located to the upper left of the LED dashboard. Table 6 on page
14 describes the POWER LED.
