SRX650 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 SRX650 Services Gateway Electrical Wiring Guidelines. |
| Caution: Power cords and cables must not block access to services gateway components or drape where people could trip on them. |
Table 1 summarizes the specifications for the power cable(s), which you must supply.
