2.4 Connect the Power
The chassis has two slots at the top of the front panel for redundant power supply modules (the OLT
can run on one). The power connections are on the front of each power module.
When connecting the OLT power wires to the power module, push the
wires firmly into the terminals as deep as possible and make sure that no
exposed (bare) wires can be seen or touched.
Use two (or four) wires of the gauge specified in Table 14 on page 28 connect each DC input to a DC
power supply to supply the operating voltage for the OLT. The connections are as follows: It is
recommended to connect input 1 to the regular DC power source and connect input 2 to a backup
DC power source such as a battery.
1 Use a screwdriver to loosen the power module screws.
2 Slide the power module out partially to expose the power terminal screws.
3 Connect power wires to the negative power terminals on the front of the power module, and tighten
the terminal screw.
4 Connect the other ends of the power wires to the –48 V terminal on the power supply.
5 Connect power wires to the positive power terminals on the front of the IES power module, and
tighten the terminal screw.
6 Connect the other ends of the power wires to the ground terminal on the power supply.
7 Push the power module back in and tighten the screws.
8 Repeat the previous steps for the second power supply module.
