Netgear GSM7228PS - ProSAFE 28 ports Gigabit Ethernet L2 Managed Stackable Switch with PoE Manual De Hardware

Connecting a Redundant Power Supply

Each switch has a redundant power supply (RPS) connector at the rear of the switch next to 
the power supply panel.

You can connect an external DC-to-DC power supply unit to the switch to provide redundant 
power in case the primary power supply fails. To connect a redundant power supply (RPS) 
unit to the switch, first turn off the switch. When the power is off, you can remove the cover 
plate and connect the RPS unit to the switch. After all connections are completed, apply 
power to the switch.

Connecting Equipment to the Switch

You can connect devices, a Gigabit Ethernet module, and/or a console to the switch. 

RJ-45 Ports

The switch uses Auto Uplink technology, which enables you to attach devices using either 
straight-through or crossover cables. Use a Category 5 (Cat5) unshielded twisted-pair (UTP) 
cable terminated with an RJ-45 connector. 

Ethernet specifications limit the cable length between the switch and 

the attached device to 328 feet (100 meters).

Connecting a Console to the Switch

After you install the switch and apply power, you can connect to it with a terminal or 
workstation. You can use the Command Line Interface (CLI) to identify the IP address. If you 
are stacking switches, see <pdf>“Creating a Stack” on page 2-24.
