Budgeting Power - Avaya P333T-PWR Recommended Redundancy Scheme

Budgeting Power

When deciding how many 800W PSUs to install in the APC external DC power
shelf, you need to take into account the configuration of the powerinline external
power parameter in the P333T-PWR switch (set using the set powerinline
external power CLI command). Refer to Table 3 for guidelines:
Table 3
No. of APC PSUs
powerinline external power = 405W (default, maximum)

3
powerinline external power = 200W (backup only)

If you set the powerinline external power parameter to other values, you need to
recalculate the number of switches supported accordingly.
Note: The Avaya P330 BUPS can support up to four P333T-PWR modules. If you are
backing up more than four P333T-PWR switches using the APC power shell,
calculate the number of P330 BUPS units needed accordingly.
