The STB NIP 2311 NIM Module
30
EIO0000000051 6/2010
Ethernet Communications LEDs
Two LEDs describe STB NIP 2311 module operations:
z PWR (power): This LED indicates whether or not the NIM’s internal power
supplies are operating at the correct voltages. The PWR LED is directly driven by
the STB NIP 2311’s reset circuitry.
z STS (status): This LED indicates whether the NIM is operating or initializing.
The PWR and STS LEDs indicate these operating conditions:
Label Pattern Meaning
PWR (green) steady on Internal voltages are all at or above their minimum voltage
level.
steady off One (or more) of the internal voltages is below minimum
voltage level.
STS (green) steady on Operational: The STB NIP 2311 is operating correctly.
NOTE: If the NIM reaches a normal operating state with a valid
IP and the Ethernet cable is removed or broken, the STS LED
remains on, indicating that the NIM still has a valid IP.
blinking
(steady)
Standby: Initializing Ethernet.
NOTE: The steady blink pattern may not be recognized until
the LED manager code has been initialized.
blink: 2 No valid IP parameters (e.g., after a clear IP rotary switch
setting).
blink: 3 <not used>
blink: 4 Duplicate IP address detected.
blink: 5 Obtaining IP address via BootP or DHCP.
blink: 6 Using default IP address for some reason other than duplicate
IP address, or waiting to be served by BootP/DHCP.
NOTE: This pattern is subordinate to blink: 4 and blink: 5.
