Chapter 6 Maintaining the Router
Removing and Replacing AC and DC Power Subsystem Components
Caution
Newer, 1900 W DC power supplies require the upgraded PDU. You cannot install
a new power supply using the old PDU. If you are replacing an old power supply
with the new unit, you must perform a complete upgrade by replacing both power
supplies, the PDU,
and the blower module
if you are required to meet NEBS
extended temperature range requirements. This also means that you must shut
down the router to perform the upgrade. Notify the system administrator and other
appropriate personnel that all routing traffic stops while the upgrade takes place.
Before you attempt to install or replace them (
Table 6-1Table 6-1
), be sure you
know your system power supplies and associated PDU.

Original and Replacement Components
Original Component
Replacement Component
AC Power Distribution Unit (PDU)
(GSR6-AC-PDU=)
Compatible only with 1400 W power
supplies.
AC PDU (12000/6-AC-PDU=)
Required for 1900 W power supplies.
AC Power Supply (PWR-GSR6-AC=)
Used to replace 1400 W power supplies only.
All power supplies must be 1400 W. Do not
mix with 1900 W power supplies.
AC Power Supply (12000/6-AC-PEM=)
Used to replace existing power supplies. All power
supplies must be 1900 W. Do not mix with 1400 W
power supplies.
If you are upgrading 1400 W power supplies to 1900
W power supplies, you must also upgrade to the new
AC PDU (12000/6-AC-PDU=).
Caution
Redundancy in 1400 W power systems
was not a requirement and used a blank
filler (MAS-GSR-PWRBLANK=) in
place of a second power supply to ensure
EMI compliance. Newer 1900 W power
supplies require redundancy. You must
install two power supplies.
