NPM Front Card
The NPM front card monitors its own activity. When a failure is detected, the fail LED is lit. In nodes
with redundant NPMs, the active NPM is indicated by an active LED, while the standby NPM will not
have a lit active LED (see Figure 2-2). To display information on any NPM from the switch software
command-line interface (CLI), use the switch software dspcd command.
Table 2-1 describes NPM front card memory and memory expansion capability for all three NPM front
card versions.The switch software image is stored in the dynamic RAM (DRAM), with non-volatile
Flash electrically-erasable programmable ROM (EEPROM) supporting switch software image
download over the attached network. Battery-backup RAM (BRAM) stores system configuration data.
