Scenario in which one UIM maps to four cabinets
Four cabinets correspond to one UIM.
Each cabinet contains only one type of intelligent device. The port for connecting the
intelligent device to the UIM must meet the physical connection rules from
Table 6-4.
 This scenario supports four types of intelligent devices: smart U space manager, rPDU, cabinet
electronic lock, and T/H sensor.
 Each port on the UIM does not support cascading.
 The UIM must be installed in the first cabinet, and the intelligent devices in the following three
cabinets need to be connected to the first cabinet.
 If the actual number of IT cabinets is not an integral multiple of 4, connect cables according to the
rules. Idle COM ports on the UIM can be reserved.
