The Cisco ASR 9006 Router and Cisco ASR 9904 Router are similar, except that:
• The Cisco ASR 9006 Router supports one power tray with up to three version 1 power modules or
four version 2 power modules.
• The Cisco ASR 9904 Router supports one power tray with up to four version 2 power modules (see
Figure 1-31).

• To operate the Cisco ASR 9922 Router on AC power, four AC power trays should be installed, each
with up to four power modules which are fed by a single-phase 220-V 20-A branch circuit. Eight
power modules are enough to power a fully-populated chassis. Sixteen power modules are required
for N+N redundancy. Fewer power modules can be used if the chassis is populated with fewer line
cards.
• To operate the Cisco ASR 9922 Router on DC power, four DC power trays should be installed, each
with up to four power modules which are fed by separate pairs of redundant –48-V 60-A branch
sources. Fifteen power modules are enough to power a fully-populated chassis. Sixteen power
modules are required for N+1 redundancy. Fewer power modules can be used if the chassis is
populated with fewer line cards.
