H3C SR6608/6604 Routers Installation Manual Chapter 3 Arranging Slots and Numbering Interfaces3-2Note:The numbers 0 through 5 in Figure 3-1 represent Slot 0 through Slot 5 on the SR6608respectively and the numbers 0 through 3 in Figure 3-2 represent Slot 0 through Slot 3on the SR6604 respectively. Actually, these numbers are not silk-screened on thedevice.3.2 Numbering InterfacesBefore installing an HIM/MIM, you must install an FIP-100/FIP-200 first. An FIP-200supports both HIMs and MIMs, while an FIP-100 supports only MIMs.The interfaces of the device are numbered in the form of interface-type X/Y/Z,Where,z interface-type: Type of the interface such as GE interface and serial interface.z X: Number of the slot where the FIP-100/FIP-200 resides, in the range of 2 to 5 onthe SR6608 and 2 to 3 on the SR6604.z Y: Sub-slot number, namely, the number of the slot where the HIM/MIM resides onthe FIP-100/FIP-200.z Z: Sequence number of the interface on the HIM/MIM.Note:z Different interface modules on the same LPU have the same slot number X.z Different interfaces on the same interface module have the same sub-slot numberY.z For each type of interface, the sequence number Z starts from 0 on the interfacemodule.z The management Ethernet interface number is permanently M-GigabitEthernet0/0/0 no matter whether the RPE-X1 (in the case of a single RPE-X1) or the activeRPE-X1 (in the case of two RPE-X1s) resides in slot 0 or slot 1.3.3 Examples3.3.1 Example 1An FIP-100 is installed in slot 3 and a 2GBE module is installed in sub-slot 2 of theFIP-100.
