Connecting AUX cable

Step 1: Plug the RJ-45 connector of the AUX cable into the AUX port of the switch.

Step 2: Plug the DB-25 (male) or DB-9 (male) connector at the other end into the serial port of the analog modem.

Introduction to RJ-45 connector

Being RJ-45 connector, the 10Base-T/100Base-TX port of the Switch 8800 Family supports MDI/MDIX auto-sensing and will be connected using the category-5 shielded cable. The following figure illustrates an RJ-45 connector.

Connecting category-5 shielded cable

Step 1: Plug one end of the network cable into the desired Ethernet RJ-45 connector on the switch.

Step 2: Plug the other end of the cable into the RJ-45 port of the peer device.

Connecting Fiber

 

All the megabit and gigabit optical modules available for the Switch 8800 Family

n are SFP modules that provide LC user ports.

 

Introduction to fiber connector

n

When selecting a fiber network facility, make sure that the type of the

 

connector and the fiber match the adopted optical port.

 

Before connecting the fiber, make sure that the receive-end optical power does

 

 

not exceed the upper threshold of the receiving optical power. Excessive

 

 

receiving optical power is very likely to burn the optical module.

 

Fiber connectors are indispensable passive components in an optical fiber

 

communication system. Their application allows the removable connection

 

between optical channels, which makes the optical system debugging and

 

maintenance more convenient and the transit dispatching of the system more

 

flexible. Among various fiber connectors, only LC connector will be introduced

 

here.
