Site Power Requirements and Heat Dissipation Chapter 2 Site Planning Site Power Requirements and Heat Dissipation Note Catalyst 2948G, 2948G-GE-TX, and 2980G switches have internal power supplies. All of the switches support Cisco Redundant Power System (RPS) for redundant operation. This section provides site power requirements and heat dissipation specifications for the Catalyst 2948G, 2948G-GE-TX, and 2980G switches. You should verify site power before you install a switch. Power requirements can vary for each Catalyst switch. Knowing the power requirements can be useful for planning the power distribution system needed to support the switches. Heat specifications are used for determining the air-conditioning requirements for an installation. Note Refer to the Site Preparation and Safety Guide for site power requirements, preinstallation requirements, and EMI recommendations. Table 2-1 describes the power requirements and heat dissipation specifications for the Catalyst 2948G, 2948G-GE-TX, and 2980G switches.

Site Power Requirements and Heat Dissipation
Note
Catalyst 2948G, 2948G-GE-TX, and 2980G switches have internal power
supplies. All of the switches support Cisco Redundant Power System (RPS) for
redundant operation.
This section provides site power requirements and heat dissipation specifications
for the Catalyst 2948G, 2948G-GE-TX, and 2980G switches. You should verify
site power before you
install a switch.
Power requirements can vary for each Catalyst switch. Knowing the power
requirements can be useful for planning the power distribution system needed to
support the switches. Heat specifications are used for determining the
air-conditioning requirements for an installation.
Note
Refer to the
Site Preparation and Safety Guide
for site power requirements,
preinstallation requirements, and EMI recommendations.
Table 2-1
describes the power requirements and heat dissipation specifications for
the Catalyst 2948G, 2948G-GE-TX, and 2980G switches.
