Installing the Series 5400zl Switches Installation Procedures 6. Install the Grounding Wire If a grounding wire is to be attached to the switch chassis, the grounding lug must be removed and a wire crimped to it and the grounding lug must be reinstalled. 1. Use a #1 Phillips (cross-head) screwdriver and remove the grounding lug and two screws from the back of the switch. 2. Crimp the grounding lug to a properly grounded grounding wire. 3. Re-attach the grounding lug to the switch with the two screws. Grounding lug Grounding lug screws Installing the Series 5400zl Switches Figure 2-11. Attaching Grounding Lug to the 5400zl Switch 7. Connect the Switch to a Power Source 1. Plug the included power cord into the switch's power connector and into a nearby properly grounded AC power source. If a redundant power source is available, it is desirable to power one switch power supply from the regular AC source, and the other power supply from the redundant AC source. This will provide redundancy in AC power to the switch, as long as the switch PoE power usage falls within the capability of one power supply. If both power supplies are plugged into a common AC source, there is still power supply redundancy, that is, protection against power supply failure, but if the AC source fails, the switch will lose all power. 2. Re-check the LEDs during self test. See "LED Behavior" on page 2-16. 2-21
