Power system
1) S3100-8TP-EI AC-powered Ethernet switches:
z Rated voltage range: 100 VAC to 240 VAC, 50 Hz/60 Hz
z Input voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz
2) S3100-8TP-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 S3100-8TP-EI cools off naturally.
S3100-26TP-PWR-EI
Front panel
S3100-26TP-PWR-EI Ethernet switches each provide twenty-four auto-sensing 10/100Base-TX
Ethernet ports, two 10/100/1000Base-T Ethernet ports, two 100/1000Base SFP ports, and one console
port. Each SFP port and the corresponding 10/100/1000Base- T Ethernet port form a Combo port. For
each Combo port, either the SFP port or the corresponding 10/100/1000Base- T Ethernet port can be
used at a time.
