Avaya P333T-PWR – Recommended Power Supply Redundancy Scheme
7
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:
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.
