Electrical installation requires connecting the switch to a power source. Each type of flexible mount has a different procedure for completing electrical connections. These are explained below.

Note

All power connection wiring should conform to the rules and regulations in the National Electrical Code (NEC), as well as any local codes.

Flexible Mount with Direct-Wired Junction Box

To complete wiring of the direct-wired junction box and to connect to a power source, follow these steps:


Note

Only a trained and qualified electrician should be allowed to perform the procedure explained below.

Procedure

Step 1

Ensure that supply wiring is not energized prior to installing the flexible mount.

Step 2

Remove screw from the direct-wired junction box to open the cover.

Step 3

Determine mounting orientation and identify the desired wiring entry and exit points from the flexible mount’s integrated junction box.

Step 4

Remove the appropriate knockout(s), either 1/2'' or 3/4" from the top or bottom, based on the connector type employed in the installation.

Step 5

Prepare an armored cable by stripping conductor ends approximately 1/2'' or 3/4".

Step 6

After preparing the cable for connection, attach the cable to an approved connector and install the connector in the appropriate knockout. Ensure that you leave a sufficient working length of wire inside the junction box.

Step 7

Strip supply wires. Remove pre-stripped insulation from wires supplied inside the flexible mount.

Step 8

Twist stripped ends of wires and secure the wires with a wire nut or other approved junction device. Supply wires are color coded: Hot-black, Neutral-white, Ground-green/yellow. Verify that connections are made with the appropriate supply wires as color codes may vary.

  • If you are combining multiple flexible mounts to form a single wiring raceway, remove the metal divider plates that separate adjoining junction boxes. Ensure that you leave the divider plates in place on either end of the raceway.

  • When you join two or more flexible mounts with direct-wired junction box, join the Hot, Neutral and Ground supply wires of one wiring box to the corresponding Hot, Neutral and Ground supply wires of the adjacent wiring box. This allows wiring multiple units to the same circuit with only a single supply wire entry point.

    Warning

     
    When combining multiple switches on a single circuit, refer to the switch ampacity tables below to verify that the number of switches is appropriate, given the circuit’s voltage and ampacity. The switch ampacity table provides number of units that fit on a single circuit (after derating to 80% of capacity), i.e. 15A circuit gives number of units possible when only 12A (80% of 15A) is used.

Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:


  • This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

  • When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Statement 1006

Note

Unit in the above warning statement refers to the rack mount chassis (CDB-MNT-RACK5-C14).

Use the following procedure to install a Catalyst Digital Building Series Switch in a rack.

Procedure

Step 1

Position the 19-inch 5RU rack mount chassis in the rack and align the mounting holes in the chassis with the mounting holes in the rack. Secure the chassis using eight 10-32 or 12-24 screws to the rack post.

Figure 41. Installation of Rack Mount Chassis on a 19-inch Rack


You can also install the rack mount chassis upside down if required for cable routing.



Step 2

Plug country-specific power cords to power connectors on the rack mount chassis. Plug the other ends of the power cords to a power source.

Figure 42.

Step 3

Slide the switches into each of the rack unit slots in a front-mounting position and secure them to the rack using the supplied screws as shown in the figure.





You must leave 2RU gap between each rack unit for ventilation unless forced air is provided top to bottom in the rack.



What to do next

After installing the switch in the chassis, complete the installation process by grounding the chassis. See Establishing the System Ground .

Establishing the System Ground

This section describes how to connect a system ground to the switch.

The system ground provides additional grounding for EMI shielding requirements and grounding for the low voltage supplies.


Note
In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations.
Required Tools and Equipment

To connect the system ground, you need the following tools and materials:

  • Grounding lug—A two-hole standard barrel lug. Supports 6 AWG wire. Supplied as part of accessory kit.

  • Grounding screws—Two 8 mm pan-head screws. Supplied as part of the accessory kit.

  • Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according to local and national installation requirements. The length of the grounding wire depends on the proximity of the chassis to proper grounding facilities.

  • No. 1 Phillips screwdriver.

  • Crimping tool to crimp the grounding wire to the grounding lug.

  • Wire-stripping tool to remove the insulation from the grounding wire.

Connecting the System Ground
To establish an earth ground for the chassis, you must attach a grounding cable from the chassis’ grounding lug to the rack.

Location of system ground lug

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.5 inch (12.7 mm) ± 0.02 inch (0.5 mm) of the covering from the end of the grounding wire.

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug.

Step 3

Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground lug.

Step 4

Place the grounding wire lug against the grounding pad, making sure that there is solid metal-to-metal contact.

Step 5

Secure the grounding lug to the chassis with two grounding screws. Ensure that the grounding lug and the grounding wire will not interfere with other switch hardware or rack equipment.

Step 6

Connect the other end of the grounding wire to an appropriate grounding point at your site or to the rack.

Installing the Power Cord Retainer

The power cord retainer (PWR-CLP=) is optionally supplied as part of accessory kit with the 5RU 19" rack mount chassis (CDB-MNT-RACK5-C14) and flexible mount with IEC C14 power junction box (CDB-MNT-FLEX-C14).

Procedure

Step 1

Choose the sleeve size of the power cord retainer based on the thickness of the cord. The smaller sleeve can be snapped off and used for thin cords.

Step 2

Slide the retainer around the AC power cord, and pass it around the loop on the switch.

10/100 Port Connections

The switch 10/100 port configuration changes to operate at the speed of the attached device. If the attached ports do not support autonegotiation, you can manually set the speed and duplex parameters. Connecting devices that do not autonegotiate or that have the speed and duplex parameters manually set can reduce performance or result in no linkage.

To maximize performance, choose one of these methods for configuring the Ethernet ports:

  • Let the ports autonegotiate both speed and duplex.

  • Set the interface speed and duplex parameters on both ends of the connection.
