power requirements. For information, see 241-7401-200 Passport 7400
Hardware Description.
Procedure steps
1 Insert the power cord connector into the appropriate power connector on
the power input panel on the rear of the switch. See “Installing 5-slot
Passport switch ac power cords” (page 257), or “Installing 16-slot
Passport switch ac power cords” (page 258).
Each ac power supply requires its own power cord. Do not use extension
cords.
The 16-slot Passport switch has three power connectors on the power
input panel, one for each possible power supply. If your switch contains
fewer than three power supplies, ensure that you install the power cord
into the power supply’s corresponding power connector.
2 Run the cord into the cable guide.
3 If your switch is in a cabinet, you can route the cable through the floor or
ceiling, with other cables. Remove the smaller grill cutout in either the top
or the bottom of the cabinet with a 3/8-inch box wrench. Route the cord
out of the cabinet through the appropriate cutout.
or
If your switch is in a standard 19-inch rack, route the cord out of the rack.
4 Run the cord to the power outlet.
5 Plug the cord into the power outlet.
The ac power cord grounds a 5-slot Passport switch, so no additional
grounding procedure is required.
WARNUNG
Verletzungsgefahr durch Stromschlag
Vergewissern Sie sich, dass die Wechselstrombuchse, an
der Passport-Switch angeschlossen ist, vorschriftsmäßig
geerdet ist, und der Erdungsstift des Netzkabels nicht
verändert wurde.
Eine nicht vorschriftsmäßig geerdete Steckdose erhöht
die Verletzungsgefahr für das Bedienpersonal und das
Risiko der Beschädigung des Geräts durch Stromschlag.
