A1 Introduction<br />
<br />
<br />
<br />
<br />
The <strong>Parvus</strong> Power Supply provides power for the Cisco <strong>5915</strong> and the expansion module boards.<br />
The internal Ethernet connection connects the Cisco <strong>5915</strong> to the COM-1268 boards in the<br />
expansion module.<br />
The Zeroization signal is externally generated at the J3 Console connector and transmitted to the<br />
Cisco <strong>5915</strong> and expansion module boards. Zeroization erases the COM-1268 application code<br />
and configuration data on both COM-1268s. For additional information, refer to "Zeroization" on<br />
page 46.<br />
From the <strong>DuraMAR</strong> <strong>5915</strong> perspective (front panel, pinouts, cables), the two COM-1268 boards<br />
are J4 ETH 1 and J5 ETH2. To the COM-1268 management interface, the two boards are<br />
boards 0 and 1 with ports 0/0-1/9.<br />
Internal Ethernet Connections<br />
Each COM-1268 has ten ports but some ports are internally connected to provide connection between<br />
COM-1268 board 0 and board 1 and between COM-1268 board 0 and the Cisco <strong>5915</strong> (Figure 24).<br />
COM-1268 management is performed via the serial management port on board 0.<br />
Commands for board 1 are sent from board 0 via IrDA (infrared). The IrDA link supports board 1<br />
port configuration, transfer of board 1 configuration files to and from a host PC, and initiating<br />
upgrading of board 1 application code.<br />
