System Overview
Each Services Router has six front panel slots for field-replaceable PIMs. These
slots are numbered from top to bottom and from left to right as shown in
the slot number diagram on the front panel, shown in Figure 8.

Gigabit Ethernet and 4-port Fast Ethernet ePIMs can be installed in high-speed slots
only. High-speed slots are indicated by a black triangle containing an E in the front
panel slot number diagram. On J4350 Services Routers, the high-speed slots are slot
3 and slot 6. On J6350 Services Routers, the high-speed slots are slots 2, 3, 5, and 6.
Slot 0 is the fixed interface module that contains the built-in Ethernet ports.
Power Button and POWER LED
The power button is located on the left side of the front panel (see
Figure 7). 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 7 describes the POWER LED.

Color State Description
On steadily Power is functioning correctly. Green
Blinking Power button has been pressed and quickly released, and
the router is gracefully shutting down.
Unlit Off Router is not receiving power.
After the router is powered on, status indicators—such as LEDs on the
front panel and
show chassis command output—can take up to 60 seconds
to indicate that the power supply is functioning normally. Ignore error
indicators that appear during the first 60 seconds.
If you need to power off the router after the Routing Engine finishes booting, use
the J-Web interface or the CLI to halt the Services Router first. For instructions,
see the J-series Services Router Administration Guide.
