WARNING: When powering any Switch 4210 from an RPS, make sure that the unit is earthed (grounded) by either connecting the power cord to the unit or by connecting the earth terminal on the rear of the unit to a reliable electrical earth (or by connecting both).
Table 15 shows the recommended System circuit breaker and cable rating for the Switch 4210. The recommended cable length should not exceed three metres (9.84 feet). Table 15 Switch 4210 Circuit Breaker and Cable Ratings WARNING: Make sure to follow the RPS Manufacturers recommendations when connecting the cable to the RPS.
The recommended cable length should not exceed three meters (9.84 feet). Using Power over The Switch 4210 Power over Ethernet (PoE) units can supply power to any IEEE Ethernet 802.3af compliant device through any of its front panel ports over a Category 5 or Category 5e Ethernet cable.
Ethernet cable does not require a separate power supply. If, for example, you use the switch to connect a 3Com 11 Mbps Wireless LAN Access Point 8500 to the network, then only a network cable is required to provide both power and network connectivity.
