Replacing a DC Power Supply on the SRX3600 Services Gateway
NOTE: For the services gateway to meet NEBS and ETSI standards, all four DC power supplies
must be enhanced DC power supplies. See “SRX3600 Services Gateway NEBS and ETSI Compliance”
on page 316 for more information.
NOTE: The same DC power supply is used in both the SRX3400 and SRX3600 Services Gateways.
However, this power supply is not interchangeable with that used in the SRX1400 Services Gateway.
The SRX1400 Services Gateway power supply will fit into the SRX3600 Services Gateway, but will
not work properly. You can identify the SRX1400 Services Gateway power supply by the plastic
air filter assembly installed over the cooling air inlet as shown in Figure 82 on page 234.

To replace a DC power supply:
1. Switch off the dedicated facility circuit breaker for the power supply being removed. Follow your site's
procedures for ESD.
2. Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance
that the cables might become active during the removal process.
