For the connection of DC power supplies, refer to Section
4.3. To connect to the 220 V AC power supply, it is
necessary to use the primary power supply system.
2.5. 2.5. 2.5. 2.5. Optional Uplink Interface Modules
The modular structure is adopted for 3P@C 4450E. Each 10U chassis has 16 slots, the former two of
which are for inserting the SMUB boards. The SMUB provides multiple optional types of uplink
interface modules to meet different user networking requirements. The following uplink interface
modules are supported:

The following describes the commonly used gigabit interface module (DS-1GLX/DS-1GSX) and the
100M interface module (DS-2FMM/ DS-2FSM/ DS-4TXB/ DS-4ITX) respectively.
2.5.1. 2.5.1. 2.5.1. 2.5.1. 1-port Gigabit Long-wave Optical Interface Module (DS-1GLX)
The DS-1GLX module provides 1 gigabit long-wave Ethernet optical interface. The physical interface
is a standard SC optical interface whose maximum transmission distance is 10 km. A pair of single-
mode fibers is required for it. The fiber length and peer interface type depend on the real situation.
