button is located next to the IO POWER OK LED or next to the auxiliary port on the I/O controller
faceplate. The CPU reset button resets the entire system.
The NPE-G2 and NPE-G1 faceplate contains LEDs that indicate system and port status. The RJ-45 and
GBIC or SFP ports share the same LINK LED because only one of these ports per interface (0/1, 0/2, or
0/3) can be used at any one time. The ENABLE LED is on if the RJ-45 port is in use. The POWER ON
LED on the NPE-G1 or the PWR OK LED on the NPE-G2 is on when the system is powered on, whether
