SRX550 High Memory Services Gateway DC Power Cable Specifications
The DC power supply in slot 0 must be powered by dedicated power feeds derived from
feed A, and the DC power supply in slot 1 must be powered by dedicated power feeds
derived from feed B. This configuration provides the commonly deployed A/B feed
redundancy for the system.
CAUTION: You must ensure that power connections maintain the proper
polarity. The power source cables might be labeled (+) and (–) to indicate
their polarity. There is no standard color coding for DC power cables. The
color coding used by the external DC power source at your site determines
the color coding for the leads on the power cables that attach to the terminal
studs on each power supply.
WARNING: For field-wiring connections, use copper conductors only.
For other electrical safety information, see “SRX550 High Memory Services
Gateway Electrical Wiring Guidelines” on page 63.
