Power Supplies
The AT-IX5-28GPX switch has two rear slots for hot-swappable power
supplies.
The switch is supplied with a factory installed blank panel that covers both
power supply slots, and with a separate blank panel to use if you only
install one power supply.
One or two AT-PWR800 (800W) power supplies can be installed in these
switches. These power supplies are illustrated in Figure 9 on page 38.
Installing two power supplies provides a switch with power redundancy
and protect against interruptions to network operations in the event one of
the power supplies loses power or fails.
The switch has a PoE budget of 720 watts when both power supplies are
active and 370 watts when only one power supply is active. For further
information, refer to “Power Budget” on page 27.
Refer to “Technical Specifications” on page 123 for the input voltage
range.
