Connect the EX4100-F to Power

Connect Earth Ground to an EX4100-F Switch

To ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements, you must connect EX4100-F switches to earth ground before you connect power to the switch. You must use the protective earthing terminal on the switch chassis to connect the switch to earth ground (see Figure 1 and Figure 2.

You must install the EX4100-F switches in a restricted-access location and ensure that the chassis is always properly grounded. EX4100-F switches have a two-hole protective grounding terminal on the rear panel of the chassis. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

CAUTION:

Ensure that a licensed electrician has attached the appropriate grounding lug to the grounding cable that you supply. Using a grounding cable with an incorrectly attached lug can damage the switch.

Before you connect earth ground to a EX4100-F switch, ensure that you have parts and tools listed in Table 1 available:

To ground the EX4100-F switch to a proper ground reference:

  1. Connect one end of the grounding cable to a proper earth ground, such as the rack in which the switch is mounted.
  2. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the rear panel (see Figure 1 and Figure 2).

  3. Secure the grounding lug to the protective earthing terminal with the screws.
  4. Secure the grounding cable and ensure that it does not touch or block access to other switch components.
    Warning:

    Ensure that the cable does not drape where people could trip over it.

Connect AC Power to an EX4100-F Switch

These instructions apply to EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, EX4100-F-48T, EX4100-24MP, and EX4100-48MP switches. Before you connect AC power, ensure that you have the following parts and tools available:

  • A power cord appropriate for your geographical location

  • A power cord retainer clip (provided with the switch)

Ensure that you have connected the device chassis to earth ground. The AC power cords also provide additional grounding when you connect the power supply in the switch to a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see Table 10).

CAUTION:

For installations that require a separate grounding conductor to the chassis, have a licensed electrician complete this connection before you connect the switch to power. For instructions on connecting earth ground, see Connect Earth Ground to an EX4100-F Switch.

You install the power supply in the power supply slot on the rear panel of the switch.

To connect AC power to the switch:

  1. On the rear panel of the switch, push the end of the power cord retainer strip into the slot above the power cord inlet until the strip snaps into place. Ensure that the loop in the retainer strip faces the power cord (see Figure 3).

    The power cord retainer clip extends out of the chassis by 3 in. (7.62 cm).

  2. Press the small tab on the retainer strip to loosen the loop. Slide the loop until you have enough space to insert the power cord coupler into the power cord inlet.
  3. Locate the power cord or cords shipped with the switch. The cords have plugs appropriate for your geographical location. See Figure 4.
    Warning:

    Ensure that the power cord does not block access to switch components and that it is secured to prevent people from tripping on it.
  4. Insert the power cord coupler firmly into the power cord inlet (see Figure 4).
  5. Slide the loop toward the power supply until it is snug against the base of the coupler.
  6. Press the tab on the loop and draw out the loop into a tight circle.
  7. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is tight against the base of the coupler and the slot in the nut is turned 90° from the top of the switch. See Figure 5 and Figure 6.
  8. If the AC power source outlet has a power switch, set it to the OFF (0) position.
  9. Insert the power cord plug into an AC power source outlet.
  10. If the AC power source outlet has a power switch, set it to the ON (|) position.
