1.7 FEATURES
Redundant Power Supply Modules
The 6C110 supports two power supply modules which reside in the slots
labeled PS1 and PS2.
Each power supply module supports an ac input connector that allows
each power supply to be connected to a separate ac power source.
Cabletron Systems also offers a power supply module that supports a dc
input connector that allows each power supply to be connected to a
separate dc power source. In addition, the power supply modules are
capable of load sharing 50% (+/- 5%) of the total load presented by the
6C110. If one of the power supply modules fails, the other power supply
module supplies the entire load of the chassis without interruption to
network traffic.
Power Supply LANVIEW LEDs
Each power supply module comes equipped with LEDs for at-a-glance
diagnostics that indicate individual power supply status and overall
chassis redundancy status. Refer to
Chapter 2 , Installation
Requirements and Specifications , for a full explanation of the power
supply LEDs and their definitions.
!
CAUTION
If the 6C110 is configured with a single power supply module, it
must be located in slot PS1.
Installing one ac power supply and one dc power supply in the
same chassis is NOT allowed.
Installing legacy 6C205-2 and 6C205-3 power supplies with
6C210-1 or 6C210-2 power supplies in the same chassis is
NOT allowed.
