12 CHAPTER 1: PRODUCT INTRODUCTION
Power system
Switch 4210s 26-port PWR support AC input or DC input.
1 AC input
■ Rated voltage range: 100 VAC to 240 VAC, 50 Hz/60 Hz
■ Input voltage range: 90 VAC to 264 VAC, 47 Hz to 63 Hz
2 DC input
■ Rated voltage range: -52 VDC to -56 VDC

Switch 4210 PWR 26-Port units are able to power attached devices using standard
802.3af Power over Ethernet. Total available power for PoE on this model is
370W, enough to power 24-Ports at full 15.4W required of the PoE standard.
3Com recommends a Redundant Power System (RPS) from Eaton Powerware for
providing DC power to the Switch 4210 PWR 26-Port. For full details, refer to
www.3com.com/rps.
Cooling system
Switch 4210s 26-port PWR each run four fans for heat dissipation.

10/100BASE-TX Autosensing Ethernet Port Status LED
There are two port status LEDs on both sides (yellow LED on the left and green LED
on the right) of the 10/100BASE-TX Ethernet port on the Switch 4210 PWR
models. They indicate the port’s active, link, duplex, and speed status.
In addition, there are an A/L LED and a D/S LED on each model of 3Com Switch
4210 Family PWR. These two LEDs indicate the port status LEDs mode. When the
A/L LED is on, the port status LEDs respectively indicate the active status and link
status of the ports. When the D/S LED is on, the port status LEDs respectively
indicate the duplex status and speed status of the ports. Either the A/L LED or the
D/S LED is on at a specific time. For details, see Figure 8.
