J-series™ Services Router User Guide
Figure 11: PIM
PIMs are removable and insertable when the router is powered off. You can install
a PIM into one of the six slots in the router chassis. If a slot is not occupied
by a PIM, a PIM blank panel must be installed to shield the empty slot and
to allow cooling air to circulate properly through the router.
For pinouts of PIM cable connectors, see "Network Cable Specifications
and Connector Pinouts" on page 551. For PIM replacement instructions,
see "Replacing a PIM" on page 518.

J4300 Power System

The J4300 Services Router uses AC power. The autosensing power supply
(see Figure 7) distributes the different output voltages to the router
components according to their voltage requirements.
The power supply is fixed in the chassis, and is not field-replaceable. It has a
single AC appliance inlet that requires a dedicated AC power feed.
For information about site power preparations, see "Power Guidelines,
Requirements, and Specifications" on page 545. For information about
connecting the router to power and ground, see "Connecting Power
to the Services Router" on page 43.

J6300 Power System

The J6300 Services Router uses AC power. You can install one or two autosensing,
load-sharing power supplies at the bottom rear of the chassis, as shown in
Figure 8. The power supplies distribute the different output voltages to the router
components, depending on their voltage requirements. When the power supplies
are installed and operational, they automatically share the electrical load.
For full redundancy, two power supplies are required. If a power supply
stops functioning for any reason, the second power supply instantly
begins providing all the power the router needs for normal functioning.
It can provide full power indefinitely.
