The following chapters give you detailed processing steps you need to set up
the 6400-S.

2 - 1

Installing the 6400-S
Physical Installation1
Anchor the equipment rack that will contain the 6400.
The equipment rack must be anchored to an unmovable support to prevent it
from falling over when one or more systems are extended in front of the rack
on slides. You must also consider the weight of any other device installed in
the rack. A crush hazard exists should the rack tilt forward which could cause
serious injury.
If AC power supplies are installed
Mains AC power disconnect
The AC power cord(s) is considered the mains disconnect for the 6400-S and
must be readily accessible when installed. If the individual server power
cord(s) will not be readily accessible for disconnection then you are
responsible for installing an AC power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be labeled as
controlling power to the entire rack, not just to the 6400-S(s). To remove all
power, two AC cords must be removed.
Grounding the rack installation
To avoid the potential for an electrical shock hazard, you must include a third
wire safety ground conductor with the rack installation. If the 6400-S power
cord is plugged into an AC outlet that is part of the rack, then you must
provide proper grounding for the rack itself. If the 6400-S power cord is
plugged into a wall AC outlet, the safety ground conductor in the power cord
provides proper grounding only for the 6400-S. You must provide additional,
proper grounding for the rack and other devices installed in it.

User Guide V2IU 6400-S Converged Network Appliance
2 - 2
Overcurrent protection
The 6400-S is designed for an AC line voltage source with up to 20 amperes of
overcurrent protection per cord feed. If the power system for the equipment
rack is installed on a branch circuit with more than 20 amperes of protection,
you must provide supplemental protection for the 6400-S. The overall current
rating of a 6400-S configured with two power supplies is less than 4 amperes.
If DC power supplies are installed:
Connection with a DC source should only be performed by trained service
personnel. The 6400-S with DC input is to be installed in a Restricted Access
Location in accordance with articles 110-16, 110-17, and 110-18 of the National
Electric Code, ANSI/NFPA 70. The DC source must be electrically isolated by
double or reinforced insulation from any hazardous AC source. The DC
source must be capable of providing up to 650 Watts of continuous power per
feed pair.
Main DC power disconnect:
You are responsible for installing a properly rated DC power disconnect for
the 6400-S system. This mains disconnect must be readily accessible, and it
must be labeled as controlling power to the 6400-S. The circuit breaker of a
centralized DC power system may be used as a disconnect device when easily
accessible and should be rated no more than 10 amps.
Grounding the 6400-S
To avoid the potential for an electrical shock hazard, you must reliably connect
an earth grounding conductor to the 6400-S. The earth grounding conductor
must be a minimum 14AWG connected to the earth ground stud(s) on the rear
of the 6400-S. The safety ground conductor should be connected to the chassis
stud with a Listed closed two-hole crimp terminal with a maximum width of
0.25 inch. The nuts on the chassis earth ground studs should be installed with
a 10 in/lbs torque. The safety ground conductor provides proper grounding
only for the 6400-S. You must provide additional, proper grounding for the
rack and other devices installed in it.
Overcurrent protection
Overcurrent protection circuit breakers must be provided as part of each host
equipment rack and must be incorporated in the field wiring between the DC
source and the 6400-S. The branch circuit protection shall be rated minimum
75Vdc, 10 A maximum per feed pair. If the DC power system for the
equipment rack is installed with more than 10 amperes of protection, you must
provide supplemental protection for the 6400-S. The overall current rating of
a 6400-S configured with two power supplies is 8 amperes.
Do not attempt to modify or use an AC power cordset that is not the exact type
required. You must use a power cordset that meets the following criteria:

Installing the 6400-S
2 - 3
•Rating: For U.S./Canada cords must be UL Listed/CSA Certified type
SJT, 18-3 AWG. For outside U.S./Canada cords must be flexible
harmonized (<HAR>) or VDE certified cord with 3 x 0.75 mm conductors
rated 250 VAC.
•Connector, wall outlet end: Cords must be terminated in grounding-type
male plug designed for use in your region. The connector must have
certification marks showing certification by an agency acceptable in your
region and for U.S. must be Listed and rated 125% of overall current
rating of the 6400-S.
•Connector, 6400-S end: The connectors that plug into the AC receptacle
on the 6400-S must be an approved IEC 320, sheet C19, type female
connector.
•Cord length and flexibility: Cords must be less than 4.5 meters (14.76 feet)
long. CAUTION Temperature: The temperature in which the 6400-S
operates when installed in an equipment rack, must not go below 5 °C (41
°F) or rise above 40 °C (104 °F). Extreme fluctuations in temperature can
cause a variety of problems in your 6400-S.
•Ventilation: The equipment rack must provide sufficient airflow to the
front of the 6400-S to maintain proper cooling. The rack must also include
ventilation sufficient to exhaust a maximum of 1023 BTU's per hour for the
6400-S. The rack selected and the ventilation provided must be suitable to
the environment in which the 6400-S will be used.
Power Supplies1
The power supply cage shown is accessed from the rear of the chassis. The
power supply cage supports up to two hot-swap power supplies (either AC
input or DC input) in a (1+1) redundant configuration. Only the DC input
version is NEBS certified. The combined output power to the 6400-S system is
470 Watts per DC supply and 500 Watts per AC supply.
DC Power Supply Interface Requirements
The DC power source may produce hazardous voltage levels exceeding -60
VDC and high energy levels above 240VA that may cause electric shock or
burns. All DC input connections should be made only by a qualified service
person to prevent injury. All wiring terminals connected to the DC input
terminal block must be fully insulated with no exposed bare metal.
The power supply will operate within all specified limits over the input
voltage range outlined as follows:

Voltage
•Minimum tolerance = -38VDC
•Nominal rating = -48 to -60VDC
•Maximum tolerance = -75VDS
