Cisco ASR 902 Hardware Installation Manual page 5

Overview
The power supply provides 550W output power for the system. The power supply is field replaceable, hot
swappable, and operates separately from the fan tray. The power supply contains a front panel with mounting
screws, a handle for insertion and removal, and two status LEDs. No ON/OFF switch is provided.
The DC PSU models supported on the router are:
• A900-PWR550-D—Uses an Euro-style three-position terminal block connector ( Figure 1-2 )
• A900-PWR550-D-E—Uses a T-shaped connector ( Figure 1-3 )
• A900-PWR1200-D—Provides 975 W output power for system 12 V power with the A902-FAN-E
module. As most of the system configurations using A900-RSP3C-200-S RSP modules require power
exceeding 550 W, we recommend using the A900-PWR1200-D power supply with A900-RSP3C-200-S
RSP modules. ( Figure 1-4 )
