1.7 S3100-SI Series Front Panel LEDs

1.7.1 Power LED

Table 1-1 Description of the power LED on S3100-SI series

LED	Mark on the panel	Status	Description
Power LED	PWR	ON	The switch is powered on.
Power LED	PWR	OFF	The switch is powered off.

1.7.2 Mode LEDs and Port Status LEDs

The A/L mode LED and the D/S mode LED are used to indicate the mode of the port status LEDs. Only one of the two mode LEDs is on at one time. When the A/L mode LED is on, it implies that the port status LEDs are indicating the Active and Link status of the corresponding ports. When the D/S mode LED is on, it implies that the port status LEDs are indicating the Duplex and Speed status of the corresponding ports.

Table 1-2 Description of the port status LEDs on the S3100-SI series

Mode LED status	Port status LEDs and their status		Description
A/L mode LED is on	Yellow LED (left)	Flashing	Data is passing through the port.
	Yellow LED (left)	OFF	No data is passing through the port.
	Green LED (right)	ON	The port is connected properly
	Green LED (right)	OFF	The port is not connected or wrongly connected.
D/L mode LED is on	Yellow LED (left)	ON	The port operates in full duplex mode.
	Yellow LED (left)	OFF	The port operates in half duplex mode.
	Green LED (right)	ON	The port operates at 100 Mbps.
	Green LED (right)	OFF	The port operates at 10 Mbps.

1.7.3 MODE button

The MODE button is a mode switch button for the status LEDs of 100 Mbps Ethernet ports. You can toggle between the A/L LED and the D/S LED by pressing this button.

After the switch is powered on, the A/L LED lights up initially. If you press the MODE button, the D/S LED lights up. After that, if you press the MODE button again within 45 seconds, the A/L LED lights up again, or else the A/L LED automatically lights up after 45 seconds.

The MODE button is convenient for you to check the current status of the ports as required. For example, if you want to learn the Duplex and the Speed status of a port, you can first press the MODE button to switch to the D/S LED, then observe the status (OFF, ON, or flashing) of the two LEDs beside the port, and finally determine the current status of the port according to the above table.

l BIDI interface card must be used in couple, i.e., if the local end uses 100Base-LX-SM1310-BIDI, the remote end needs to use 100Base-LX-SM1550-BIDI.

l An S3116C or S3126C switch can accommodate only one ONU card (000Base-PX10/20)

Chapter 2 Installation Preparation

2.1 Precautions

To avoid any device impairment and bodily injury because of improper use, please take the following precautions:

l Before cleaning the switch, pull out the power plug of the switch. Do not clean the switch with wet cloth or liquid.

l Do not place the switch near water or in a damp area. Prevent water or moisture from entering the switch chassis.

l Do not place the switch on an unstable case or desk, because the switch might be damaged severely in case of a fall.

l Keep the switch room drafty and the switch ventilation hole free of obstruction.

l The switch can operate normally only under correct voltage input. Make sure that the operating voltage is consistent with that labeled on the switch.

l To prevent electric shock, do not open the chassis while the switch is operating, and do not open the chassis arbitrarily even when the switch is powered off.

l Before changing interface board, wear ESD-preventive wrist strap to prevent the board from being damaged by electrostatic discharge.

2.2 Requirements on Environment

S3100-SI series must be used indoors. When you install your switch in a cabinet or install it directly on a workbench, you must ensure:

l Enough space is left near the air-intake hole and the ventilation hole of the switch for the heat dissipation of the switch chassis.

l The cabinet or the workbench takes good ventilation and heat dissipation system.

l The cabinet or the workbench is solid enough to bear the weight of the switch and the accessories.

l The cabinet or the workbench is well grounded.

To ensure normal operation and to prolong the life span of the switch, the following requirements on the installation site must also be satisfied.

2.2.1 Temperature/Humidity Requirements

You should keep your equipment room within the proper temperature and humidity ranges to ensure the normal operation and working life of your switch. If the humidity in the equipment room is too high for a long time, it may decrease the insulation attribute of insulating material or even cause electric leakage of insulating material, and, sometimes, may change the mechanical performance of material and cause the rustiness and corrosion of metal parts. If the relative humidity is too low, the captive screws may become loose due to the shrinking of insulation washers; in addition, electrostatic is more likely to be produced in a dry environment, which may damage the circuit of the switch. High temperature may cause even greater damage to the switch. High temperature for a long time will speed up the aging of insulation material, greatly lower the reliability of the switch and greatly reduce the life span of the switch.

2.2.2 Cleanness Requirements

Dust is a potential hazard to the safe operation of the switch. Falling on the equipment, it may cause electrostatic adsorption, and hence result in poor contact of the metal connectors or connection points. This is more likely to happen when the indoor relative humidity is low; in this case, it may not only shorten the device’s working life, but also incur communication failure. The requirements on dust content and particle diameter in the equipment room are shown in the following table:

Table 2-1 Requirements on dust content in the equipment room

Physical active substance	Unit	Content
Dust particle	particle/m³	≤ 3 x 10⁴ (No visible dust on desk in three days)
Note: Dust particle diameter ≥ 5µm

Besides the requirements on dust, rigorous requirements are also set on the content of chloride, acid, and sulfide in the air of the equipment room. These kinds of harmful gas will accelerate metal corrosion and aging of certain parts. The equipment room should be protected from the intrusion of harmful gases such as SO₂, H₂S, NH₃ and Cl₂. The limits of these kinds of harmful gas are shown in the following Table.

Table 2-2 Limits on harmful gas in the equipment room

Gas	Max content (mg/m³)
SO₂	0.2
H₂S	0.006
NH₃	0.05
Cl₂	0.01

2.2.3 Anti-interference Requirements

A switch in use may be affected by the interference from outside the system by way of capacitance coupling, inductance coupling, electromagnetic radiation, public impedance (including the grounding system) coupling or conducting line (power line, signaling line and transmission line etc.). Ther
