Product Overview
Physical and Functional Description of Router
Optional AC Power Shelf
The power subsystem consists of a double-level AC-input power shelf with bays
for 4 AC-input power supplies.
Figure 1-4
shows the optional power shelf. It
attaches to the top of the router chassis and is secured to the chassis the same way
as the standard AC-input power shelf.
A router equipped with the optional AC-input power subsystem stands 77.5 inches
Note
(196.85 cm) tall and does not fit in a standard 7-foot (2.1 m) rack.
The 4 power supplies in the optional power shelf participate in an N+2 redundant
current-sharing scheme in which current sharing is divided among all 4 power
supplies. Up to two power supplies can fail and the system can continue to operate
temporarily, (depending on your system configuration) using the remaining two
power supplies. Failed supplies should be replaced as soon as possible to ensure
full redundancy.
To ensure that the chassis configuration complies with the required power

budgets, use the on-line power calculator. Failure to properly verify the
configuration may result in an unpredictable state if one of the power units fails.
