New Features in Junos OS Release 10.4 for SRX Series Services Gateways and J Series Services Routers
Hardware Features—SRX3400 and SRX3600 Services Gateways
Enhanced DC Power Supply
The enhanced DC power supply for the SRX3400 and SRX3600 Services Gateways is
an alternative to the standard DC power supply. The enhanced DC power supply helps
your services gateway meet the following NEBS and ETSI standards:
GR-63-CORE
ETSI 300019-2-1
ETSI 300019-2-2
ETSI 300019-2-3
GR-1089-CORE
Each enhanced DC power supply provides up to 1200 watts of power. In the SRX3400
Services Gateway, the enhanced DC power supply lets you configure your device with
more Services Processing Cards (SPCs), Network Processing Cards (NPCs), or I/O cards
(IOCs) than is possible with the standard 850-watt DC power supply.
NOTE: Mixing of standard and enhanced DC power supplies within the same
chassis is not supported. All installed DC power supplies must be either of
standard or enhanced types.
Table 8 on page 107 shows the different SPC, NPC, and IOC configurations applicable to
the standard and enhanced DC power supplies in the SRX3400 Services Gateway.
