Installation ManualH3C S3600 Series Ethernet Switches Chapter 3 Installation3-17Caution:Read the mark for the port to be connected carefully to make sure it is the right port.Note:The serial ports on PCs do not support hot swapping. Therefore, do not insert orremove a serial interface cable from a PC that is connected to a switch with power. Inconnecting a PC to the switch, first connect the DB-9 connector of the console cable tothe PC and then the RJ-45 connector to the switch. In disconnecting them, remove theRJ-45 connector prior to the DB-9 connector.3.5 Connecting and Removing Special Stack InterconnectCables3.5.1 Special Stack Interconnect CablesAs shown in Figure 3-23, the special stack interconnect cables, 1.5 meters (59.1 in)long, are used to connect fabric ports (1000Base-X SFP ports on the front panel) in anintelligent resilient framework (IRF) consisting of multiple S3600 series.(1) Connector of special stack interconnect cables (2) Cable clampFigure 3-23 Special stack cablesIn the case of stack connection, besides special stack interconnect cables, thecombination of SFP modules with cables or optical fibers is permissible. For the modelsof SFP modules, see Table 1-5.3.5.2 Connecting Special Stack Interconnect CablesFollow these steps to connect special stack interconnect cables:
