2) S3100-16TP-EI DC-powered Ethernet switches:
z Rated voltage range: –48 VDC to –60 VDC
z Input voltage range: –36 VDC to –72 VDC
Cooling system
The S3100-16TP-EI cools off naturally.
S3100-8TP-EI
Both AC-powered switches and DC-powered switches are available to this model.
Front panel
S3100-8TP-EI Ethernet switches each provide eight auto-sensing 10/100Base-TX Ethernet ports, one
auto-sensing 10/100/1000Base-T Ethernet ports, one 100/1000Base-X SFP ports, and one console
port. The SFP port and the auto-sensing 10/100/1000Base- T Ethernet port form a Combo port. For the
Combo port, either the SFP port or the 10/100/1000Base- T Ethernet port can be used at a time.
S3100-8TP-EI Ethernet switches have the same front panel, as shown in
Figure 1-30.
