Page 27: Preparing For Installation
Safety Precautions Before you install or remove any components from the Switch or carry out any maintenance procedures, you must read the 3Com Switch Family Safety and Regulatory Information document enclosed with your switch. To avoid damage to human body and devices, please read the following safety recommendations carefully before installing the Switch 4210G. -
Page 28: Temperature/Humidity
Temperature/Humidity You must maintain a proper temperature and humidity in the equipment room. Long-term high humidity may lead to bad insulation, electricity leakage, mechanical property changes, and metal corrosion. However, if the relative humidity is two low, captive screws may become loose as the result of contraction of insulation washers and static electricity may be produced in a dry environment to jeopardize the circuits on the device. -
Page 29: Laser Safety
Keep the device far from radio transmitting stations, radar stations, and high-frequency devices. Use electromagnetic shielding when necessary, for example, use shielded interface cables. Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes. Laser Safety The Switch 4210G are Class 1 laser devices. -
Page 30: Installing The Switch
When you ask your sales agent to maintain the switch, you must ensure that the dismantlement-preventive seal on a mounting screw of the 3Com switch chassis is intact. If you want to open the chassis, you should contact the agent for permission. Otherwise, you will bear any consequence resulted from your actions without permission. -

Page 38: Connecting The Grounding Cable
Connecting the Grounding Cable Correctly connecting the chassis grounding cable is crucial to the lightning protection and electromagnetic susceptibility (EMS) of a switch. The power and grounding terminals in this section are for illustration only. The power input end of the switch is connected with a noise filter, whose central ground is directly connected to the chassis, forming the so-called chassis ground (commonly known as PGND). -
Page 39: Where A Grounding Conductor Can Be Buried
Step1 Cut the PGND cable to a proper length according to the distance between the switch and the grounding strip. Step2 Peel 5 mm (0.20 in.) of insulation sheath using a wire stripper, and then insert the naked metal part through the black insulation covering into the end of the OT terminal. -

IRF members Power off the — switches Use cables to connect 10 G ports of the interface modules:... - Page 49 Configure the physical connection mode IRF supports two physical connection modes: daisy chain connection and ring connection. A ring connection is more reliable than a daisy chain connection. The failure of one link in a ring connection does not affect the function and performance of the IRF, whereas the failure of one link in a daisy chain connection causes the split of the IRF.
- Page 50 When 2-port interface modules are used to constitute an IRF of switches and the ports are not assigned to any aggregation group, ports of the interface module in slot 1 (MOD 1) can be connected to ports of MOD 1 or MOD 2. However, the left port can be connected to only the right port of another interface module, that is, two ports at the same side cannot be connected, as shown Figure 3-27.
