Connecting an SRX5600 Services Gateway DC Power Supply Cable
To install a replacement power cable for a DC power supply (see Figure 120 on page 265 ):
1. Locate a replacement power cable that meets the specifications defined in “DC Power Cable
Specifications for the SRX5600 Services Gateway” on page 58 .
2. Verify that a licensed electrician has attached a cable lug to the replacement power cable.
3. Verify that the INPUT OK LED is off.
4. Secure the power cable lug to the terminal studs, first with the flat washer, then with the nut. Apply
between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut, (see Figure 120 on page 265 ).
5. Route the power cable along the cable restraint toward the left or right corner of the chassis. If needed,
thread plastic cable ties, which you must provide, through the openings on the cable restraint to hold
the power cables in place.
6. Make sure the cable is not touching or in the way of any device components, and that it does not drape
where people could trip on it.
7. Replace the clear plastic cover over the terminal studs on the faceplate.
