42 About Your SystemTiering the Avocent iKVM Switch From a Digital KVM SwitchThe iKVM switch may also be tiered from a digital KVM switch such as theDell 2161DS or 4161DS, or a supported Avocent digital KVM switch. Manyswitches may be tiered without the need for a SIP (see Table 1-9).To tier the iKVM switch module from a Dell 2161DS, 180AS, or 2160ASconsole switch:• If the switch does not require a SIP to connect to the iKVM (see Table 1-9 ),connect a Cat5 (or newer) cable to the RJ-45 ACI port on the iKVMmodule. See Figure 1-18.Connect the other end of this cable to the ARI port on the external switch.• If the switch requires a USB SIP (see Table 1-8), connect a USB SIP to theiKVM, then connect a a Cat5 (or newer) cable to the SIP. Connect theother end of this cable to the ARI port on the external switch.Once the KVM switch is connected, the server modules appear in OSCAR.NOTE: Once the local system is set up, you must also resynchronize the server listfrom the Remote Console Switch software in order to see the list of blades. SeeResynchronizing the Server List at the Remote Client Workstation.Table 1-9.
