To verify that the UPS unit’s maximum wattage is not exceeded, calculate the total power consumption of all units connected to the Advanced RPS. If the result is less than 325 watts, your conﬁguration is safe if the result is greater than 325 watts, then there are too many units connected to the Advanced RPS Page Table 3-1 Gigabit Ethernet Maximum Cable Lengths MAKING CONNECTIONSConnecting a Power WorkgroupAggregating ServersYou can use the Hub 1000 SX downlinks to aggregate 10/100 Mbps SwitchesThe Hub 1000 SX does not support bandwidth aggregation trunking Aggregating3-4 CHAPTER 3 MAKING CONNECTIONS Figure 3-3 Aggregated Switches ConnectionFigure 3-4 Mixed Connection ConnectingThe best use of the hub uplink is as a backbone connection to a 3Com Solution Figure 3-6 Uplink Connection to a 10/100 Mbps SwitchTable 3-2 Troubleshooting Tips SymptomUSING THE CONSOLE PORT Console Port Connecting theWith Power RequirementsConnecting the Console Port A-3 from powerWith Power To connect the console port when the hub is disconnectedmessage, return the hub to the supplier Logging OnAfter 4 minutes of inactivity, the CLI logs off automatically Conﬁguring PasswordPort Settings Changing theTo display the Port Conﬁguration menu Table A-2 Port Conﬁguration Menu Configuring Port SettingsA-8 APPENDIX A USING THE CONSOLE PORT Configuring Port Settings and be conﬁgured to receive pause frames Configuring Port Settings A-11 Table A-3 Hub Status Information DisplayingHub Status matrix, Y indicates yes and n indicates no.
