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.

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,
