Powering the Modular Switch

Figure 17: Power Input Sockets

The power supplies require power cables that comply with IEC-320 C19 plug. The accessory kit

provides 14 AWG, C19 to C20 power cables.

To insert a power cable:

1. Pull the retaining clip back on each power input socket.

Note: The retaining clip is optional (if provided).

2. Plug the power cables into the sockets.

3. Adjust the retaining clips if needed for your power cords (if retaining clip was provided).

4. Push the retaining clip back down over the cable (if retaining clip was provided).

Cabling the DC Power Supply

Figure 18: Secondary Ground Pads displays the location of the secondary grounding pads on front

panel (left illustration) of the switch chassis. After mounting the switch into the rack, connect the at

least one of the secondary grounds to the data center ground. After the switch is grounded, ESD wrist

straps can be grounded by connecting them to one of the attach points.

Important: Grounding wires and grounding lugs (M4 x 0.7) are not supplied. Wire size should

meet local and national installation requirements. Commercially available 4 AWG wire is

recommended for installations in the U.S.

À la terre et de mise à la terre fils cosses (M4 x 0.7) ne sont pas fournis. Calibre des fils doit

satisfaire des exigences de l’installation locale et nationale. Disponible dans le commerce des

câbles 4 AWG sont recommandé pour les installations aux États-Unis.

Important: The -48V and Battery-Return leads are a pair and should run adjacent to each

other and be approximately the same length.

Le - 48V et câbles de batterie-retour sont une paire courir à côté de l'autre et doivent être à peu

près la même longueur.
