RPSU Connector
The RPSU connector allows you to connect a backup power supply unit to the
switch. Nortel Networks provides an (optional) high-power redundant power
supply unit (HRPSU) for this purpose. The HRPSU is a hot-swappable power
supply unit that provides uninterrupted operation to up to four BayStack 450
switches in the event that any of the switch power supplies fail.
Nortel Networks provides the HRPSU power rack (Order No. AA0002001) with
four slots for power supply modules (Order No. AA0005003). Each HRPSU can
support up to four BayStack 450 switches. Installation instructions are provided
with the HRPSU.
Contact your Nortel Networks sales representative for more information about the
HRPSU.
