Cabling and Power-Up:
FlexPointTM Powered Chassis
User’s Manual
1. Insure that both FlexPoint Chassis power supply switches are in the OFF position.
2. Assure that the 48VDC circuit breaker can supply 3Aof current per power supply.
3. Locate the 48VDC circuit breaker, and switch the 48VDC circuit breaker to the
OFF position.
4. Cut the power cable to the length required.
GENERAL DESCRIPTION
5. Strip approximately 3/8 of an inch of insulation from the power cable wires.
6. Connect the power cables to the FlexPoint Chassis by fastening the stripped
ends to the 48VDC connector.
The FlexPointTM Powered Chassis is a chassis capable of holding up to 14
FlexPointTM media converter modules. It is equipped with two power supplies in a
power-redundant configuration.
WARNING: Note the wire colors used for making the positive, negative and
ground connections. Use the same color assignment for the connection at the
circuit breaker.
7. Connect the power cable to the circuit breaker and switch the circuit breaker
ON.
8. Turn both FlexPoint Chassis power supply switches on and check the power
LED’s on the front panel of the powered chassis. The two LED’s should be ON.
9. Attach the L shaped tabs to the FlexPoint media converter units to be inserted
into the chassis, Secure the FlexPoint module using the enclosed screws.
10. Save the unused tabs in a safe place or secure them to the chassis’ unused
Slots.

The Powered Chassis is intended to be used with two power supplies in a power-
redundant operation. A failure of a single supply should not disturb the operation
of the chassis unit. However, certain power supply failures may cause a
secondary failure to the associated fan and cause undesired overheating of
the chassis unit.

Flat-head screwdriver (not supplied)
Wire cutter/stripper (not supplied)
Three-conductor 14 AWG copper power cable (recommended; not supplied)
SITE PREPARATION REQUIREMENTS
Preparation:
1. Power: Assure the 48VDC power can supply 3A of current.
Assure that the FlexPoint Chassis is physically installed in accordance with
the Site Preparation Requirements outlined earlier in this document.
2. The operating temperature of this equipment is 0-40 degrees C. If installed
in a closed or multiunit rack assembly, the operating ambient temperature
of the rack must not exceed the maximum rated 40 degrees C temperature.
3. Installation of the equipment should be such that the air flow in the front and
back of the unit is not compromised or restricted.
4. Never use this equipment to carry any weight except its own, never use it as
a shelf to support weight of other equipment.

may cause injury or death. Always make sure that the rack you are installing
this equipment into is properly secure, stable, balanced and designed to
carry the weight and weight distribution of this equipment.
WARNING REGARDING EARTHING GROUND:
a) This equipment shall be connected to the DC supply system earthing
electrode conductor or to a bonding jumper from an earthing terminal bar
or bus to which the DC supply system earthing electrode is connected.
b) This equipment shall be located in the same immediate area (such as,
adjacent cabinets) as any other equipment that has a connection
between the earthed conductor of the same DC supply circuit and the
earthing conductor, and also the point of earthing of the DC system. The
DC system shall not be earthed elswere.
6. When rack-mounting this equipment, the rack should be appropriately
earth-grounded.
c) The DC supply source is to be located within the same premises as this
equipment.
7. This equipment requires 48 VDC / 3.0 Amps per power supply. Appropriate
