Required tools and equipment

Required tools and equipment for installation

To install the C3100/C6100 system components in an equipment rack, you need the following tools and equipment:

Phillips screwdrivers (#0, #1, and #2)
#10-32 steel screws for fastening the C3100/C6100 to the rack
Antistatic wrist strap and grounding leash
Caution
The C3100/C6100 uses electronic components that are sensitive to static electricity. Static discharge from your clothing or other fixtures around you can damage these components. Wear an antistatic wrist strap and grounding leash so that you are appropriately grounded before touching any electronic components.

Required wiring for a DC power supply

Network Appliance does not supply the three-conductor power supply cable that connects to a DC power source. To connect the DC terminals on the power supply to the DC power source, you must fabricate a three-conductor cable that meets the following requirements.

Recommended wire gauge

12 AWG with color-coded insulation. Use the color coding scheme used by the facility in which the C3100/C6100 is installed.

Ring terminals

Each wire should be terminated with a ring terminal that accommodates #6 screws and has the following properties:

Outer ring maximum diameter--0.30 inch
Inner ring--Clearance hole for #6-32 stud
Insulated grip sleeve

Maximum distance between power supply and source

The following table lists the maximum distance between the power supply and the DC source based on wire length calculations for 12 AWG wire. You can use lower number gauge (higher current capacity) wire if a proper size terminal lug is available.

Note
For detailed information about calculating DC wire lengths, see Calculating the length of the DC wires.

Wire type

Maximum distance1,2

12 AWG (2.05 mm diameter) copper wire

47 ft (14.3m) at 25° C or

38.5 ft (11.7m) at 70° C

Wire type	Maximum distance1,2
12 AWG (2.05 mm diameter) copper wire	47 ft (14.3m) at 25° C or 38.5 ft (11.7m) at 70° C

¹ Maximum distance is equal to half the calculated maximum wire length. This is because the wire length includes the distance from one power supply terminal to the DC bus and back to the power supply. For example, a maximum distance of 47 feet corresponds to a maximum wire length of 94 feet.

² Calculated wire length is based on a 2V allowed input voltage drop and a maximum input current of 12A (at input voltage Vmin of 40V).

To configure your system, you need the following equipment:

Network Appliance supports the following types of console/terminal devices:
- ASCII terminal (also referred to as an ANSI terminal)
- Serial concentrator
- Communications server
  Note
  To use a serial concentrator or communications server, you need the documentation for those devices.
Null modem cable (optional)
Note
If the DB-9 to DB-9 straight-through serial cable for an ASCII terminal connection provided with your C3100/C6100 is not compatible with your terminal connector, you need a null modem cable or a DB-9 to DB-25 serial cable.
