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.
