Chapter 4   Cabling the Modular Switch

4.1

Grounding the Switch

After mounting the switch into the rack, connect the switch to the data center ground. 

Figure 12

 

displays the location of the grounding pads located on both sides of the power input sockets.

After the switch is grounded, ESD wrist straps can be grounded by connecting them to one of the ESD 

grounding ports located between the power input sockets, (

Figure 12

) or the rear panel (

Figure 13

 

depicts the location on the 7504. Receptacles are available in similar locations on other switch models).

Connecting Power Cables

Important!

Installation of this equipment must comply with local and national electrical codes. If necessary, consult 

with the appropriate regulatory agencies and inspection authorities to ensure compliance.

The switch operates with four power supplies, each of which connects to circuits that provide 200-240 

VAC, 50 or 60 Hz, and 20 A.
• DCS-7508 / 7508E requires the connection of at least two power supplies to active circuits.

• DCS-7504 / 7504E requires the connection of one power supply to an active live circuit.
Connecting power to all four power supplies protects against up to two failed power supplies and can 

provide grid-level redundancy. Energizing any power supply causes all power supply fans to function.
