Guidelines for Branch Circuits

!
Caution
2-4
Power for the rack system must come from a totally dedicated circuit
breaker. Do not plug any other electrical device into an outlet connected to
the circuit breaker serving the rack equipment.
Note
Data loss can occur if the circuit is overloaded and the circuit
breaker trips.
All branch circuits for the system must come from the same circuit breaker
panel. Failure to do this can cause power to flow in the data cables
interconnecting various devices of the system.
You must attach H.110 power inputs to approved Telephone
Network Voltage (TNV) branch circuits only. TNV branch
circuits must comply with all requirements called for in these
safety standards:
IEC 950/EN60 950
UL #1950
CSA #950
Attaching the inputs to non-TNV approved power sources
causes the system to fail compliance with safety regulations
and may cause damage to the system backplane and system
components.
Do not overload branch circuits. Check the manual and/or rating plate of
all devices and verify that the sum of the ampere ratings do not exceed two-
thirds of the branch rating.
Laser printers and some other devices cause periodic short duration heavy
loads that do not appear in their ampere ratings. Connect these devices on
a separate branch circuit from the system chassis.
