4.5 Connect SFP & Ethernet Cable
As required for your installation, connect the SFP or Ethernet cables used for backhauling or
debugging. Refer to Figure 4-11.
Figure 4-11: SFP & Ethernet Interfaces
4.6 Connect Ground Cable
Review the ground cable specifications provided in Table 3-1, and the lightning and grounding
guidelines described in section 3.3. Since each installation site is different, the installer must
determine the appropriate length of the cable.
The SmartUPS has 2 grounding screws that are located on the bottom of the unit. Unscrew one of
the grounding screws, connect the ground cable, and then fasten the screw securely. The other end
of the ground cable needs to be connected to a good grounding point (earth).
4.7 Turn on Battery Switch & Check LEDs
Turn on the battery switch (Figure 4-12) before closing the wiring cavity cover, which is covered in
the next section.
