2-1-2. Installing Chassis to a 19-Inch Wiring Closet Rail
Caution: Allow a proper spacing and proper air ventilation for the cooling fan
at both sides of the chassis.
⇒
Wear a grounding device for electrostatic discharge.
⇒
Screw the mounting accessory to the front side of the switch (See Fig. 2-2).
⇒
Place the Chassis into the 19-inch wiring closet rail and locate it at the proper
position. Then, fix the Chassis by screwing it.
2-1-3. Cabling Requirements
To help ensure a successful installation and keep the network performance
good, please take a care on the cabling requirement. Cables with worse
specification will render the LAN to work poorly.
2-1-3-1. Cabling Requirements for TP Ports
⇒
For Fast Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters.
⇒
Gigabit Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of
100 meters. Cat. 5e is recommended.
2-1-3-2. Cabling Requirements for 1000SX/LX SFP Module
It is more complex and comprehensive contrast to TP cabling in the fiber
media. Basically, there are two categories of fiber, multi mode (MM) and single
mode (SM). The later is categorized into several classes by the distance it supports.
They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there
mainly are LC and BiDi-SC.

Gigabit Fiber with multi-mode LC SFP module

Gigabit Fiber with single-mode LC SFP module

Gigabit Fiber with BiDi-SC 1310nm SFP module
