Engineering Guidelines

GENERAL

This section provides engineering guidelines for network designers who are incorporating an
MX410 or MX412 system into their network.

POWER REQUIREMENTS

Table 2-1 provides the current draw at –48 VDC (operating range of –42 VDC to –60 VDC) and
±24 VDC (operating range of ±22 VDC to ±27 VDC) with redundant PSUs installed.
