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 Supplies

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:
