• The terminals are marked "+" and "-".
• The size of the two screws in the terminal block is M3.5; the pitch between each screw
is 9.5mm.
Warning: Make sure that you connect the cables between the W310 and the external power
supply correctly:
Positive ("+") to positive ("+")
Negative ("-") to negative ("-")
Warning: Make sure that you use cable conductors that have the ampacity of not less than
125 percent of the total conducted load.

Recommended Power Supply Redundancy Scheme

In order to ensure full power supply redundancy for both data switching and Inline power,
you can use an external Inline DC power supply shelf (made by Advanced Power
Conversion (APC), providing isolated 54 VDC) that also provides additional Inline power
(see Figure 5.2).
Avaya recommends using the APC (Advanced Power Conversion PLC) Front End AC-
DC Power Shelf (catalog number APC-R2400A111) populated with APC 800W PSUs
(catalog number APC-A0800-085-545-CA1).
This power shelf can house up to three 800W power supplies, yielding up to 2,400W of
external power. It can provide up to 300W of Inline power per W310 switch. In a fully
populated power shelf configuration, you can provide additional backup power for eight
W310 switches (depending on configuration -- see Table 3).
