Connecting the Equipment
We recommend discharging static electricity of twisted pair cable before connecting it to the switch.
Also see below for how to install the USB memory.
2.3.1
Discharging Twisted Pair Cable
Discharge static electricity of the twisted pair cable through the ground wire cable (ground wire for power supply,
buildings, etc.) using static electricity removal tool, before connecting twisted pair cable to the switch.
Precautions
• Unplug both ends of the twisted pair cable from equipments (HUB, router, and workstation) during discharging
operation.
• Do not use ground wire of electronic devices. Use grounded cable for power supply or buildings.
• Do not short circuit with AC power supply when using ground wire for power suppl.
2.3.2
Cleaning SFP Module / SFP+ Module / Optical Connector
When invisible small dust is adhered to SFP module / SFP+ module / optical connector, optical signal will be shut or space
caused by dust will impede transmission of optical signal.
Therefore, clean up SFP module / SFP+ module / optical connector before connection.
Cleaning of SFP Module / SFP+ module
Below describes the case of SFP+ module.
1.
Blow dust away with cleanly dry air or nitrogen.
Check end face, and conduct operation below if dust is left.
2.
Lightly dampen a cleaning stick (1.25mm across, for LC/MU) with isopropyl alcohol. After wiping off
dust, slowly and carefully wipe off alcohol with a new and dry cleaning stick.
3.
Insert a cleaning stick to the optical connector insertion part of SFP module, and slowly wheel it.
4.
Insert and slowly wheel a new cleaning stick, and dry the SFP module.
5.
Check if the dust is removed with 200-fold magnification fiber scope.
