Nortel Secure Router 8012
Hardware Description
4-18 Nortel Networks Inc. Issue 5.3 (6 April 2009)
z
encapsulates and decapsulates the data frame after high-speed interface control packets
enter the network process module
z
periodically detects the state of the network process module and queries the board
version
z
updates the Erasable Programmable Logic Device (EPLD) and FPGA, and implements
the online loop and offline loop of FPGA in the board
z
monitors the temperature
z
supports resetting of the service interface board and other main modules
z
supports the CABwatch debugging tool provided by IBM

Table 4-12 describes the NPU indicators.
Table 4-12 Description of the NPU indicators
Component Description
RUN (green) The running LED. Blinking means the NPU works normally. Constant
OFF means the NPU is not in position or failed.
ALM (red) The alarm LED. Constant ON means NPU failed.
The NPU does not provide external interfaces.
