Initiate OIR Pushbutton
Initiate OIR Pushbutton
The PRP front panel includes an OIR pushbutton (see item 1 in #con_1092858/fig_1092874). Pressing the
OIR button initiates the OIR process and avoids the loss of card information caused by a surprise extraction.
If a card is extracted without initiating the OIR process (surprise extraction), the saving of logs or other
important information is not possible. Although surprise extraction is supported, using the OIR process allows
you to save important card information and logs.
After pressing the button, the OIR Ready LED (item 2 in #con_1092858/fig_1092874) blinks during the OIR
process. When the OIR process is complete, the OIR Ready LED glows solidly to indicate that the board is
ready for extraction.
If for some reason the OIR process cannot be completed, the OIR Ready LED will continue blinking. If this
occurs, you should check the log and console messages for a failure reason.
If the card is not removed within five minutes, the PRP resets itself and the OIR Ready LED will stop glowing.
The OIR process operates as described even if the PRP is not in a redundant configuration or if the standby
PRP is not ready.
Control and Management Ports
Two Control Ethernet optical ports (CNTL ETH 0, CNTL ETH 1) provide connectivity to network control
systems. These ports use small form-factor pluggable (SFP or SFP+) modules to provide external Gigabit
Ethernet (GE) or 10-Gigabit Ethernet (10-GE) connections.
A Management RJ45 port (MGMT ETH) provides connectivity to network management systems.
