Managed Stackable Switches GSM7200PS and GSM7300S Series Hardware Installation Guide
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.
Figure 2-19 Redundant Power Supply
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.
Note:
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.
