Product Characteristics

1.4.1.1.2.2.3 Comprehensive Security Measures

The S2700 guarantees the security of network devices and data transmission. It provides the following security

measures to protect the network against attacks initiated by malicious users:



Packet filtering based on MAC addresses



Various ACL policies



Mechanism of searching the forwarding table based on VLAN IDs and MAC addresses



Traffic suppression

In addition, the S2700 provides the following functions to ensure secure login of users:



Providing login passwords and password encryption for login users



Protecting commands through users levels and command levels

Product Characteristics

1.4.1.1.2.2.5 Energy-Saving Design

The S2700 adopts the following measures to save energy:



It adopts natural heat dissipation so that power consumed by fans is saved.

NOTE:

Currently, The S2700-9TP-PWR-EI, S2700-9TP-SI/EI, S2700-18TP-SI/EI, and SS2700-26TP-SI/EI supports natural heat

dissipation.



The chip switches to the power saving mode when no connected device is detected on a service interface, that

is, the interface is idle.



It uses highly-integrated and energy-saving chips produced through advanced processing techniques. With the

help of the intelligent device management system, the chips not only improve system performance but also

greatly reduce power consumption of the entire system.

Natural heat dissipation has the following advantages:



The product reliability is high.



There is no noise pollution.



You do not need to maintain the fans, which saves the maintenance cost.



The system does not have additional power consumption generated by fans, which improves the power

efficiency.



Boards are prevented from being eroded.

1.4.1.1.2.2.7 Intelligent PoE Power Supply

The S2700 PoE switches has the PoE function. It provides centralized power supply for the attached IP phone,

wireless access point (AP), portable device charger, POS machine, camera, and data collector through twisted

pairs.

The PoE function of the S2700 PoE switches complies with IEEE 802.3af and IEEE 802.3at. The S2700 can

provide power for the devices of different vendors remotely. In IEEE 802.3at, the maximum power supply

capability is 30 W. This capability ensures adequate power for IP video phone, dualband WiFi AP, IP camera,

multi-function STB11, and RFID and simplifies the network.

The S2700 PoE switches has the ability to control power supply based on time range, thus effectively managing

network devices, reducing power consumption, and lowering the OPEX.

NOTE:

By default, a combo port works in auto mode, in which the port type is determined as follows:



If the optical port has no optical module installed and the electrical port has no network cable connected, the port type depends on

which port is connected first. If the electrical port is connected by a network cable first, the electrical port is used for data switching.

If the optical port has an optical module installed first, the optical port is used for data switching.



If the electrical port has a network cable connected and is in Up state, the electrical port is still used for data switching when the

optical port has an optical module installed.



If the optical port, no matter in Up or Down state, has an optical module installed, the optical port is still used for data switching

when the electrical port has a network cable connected.



If the optical port has an optical module installed and the electrical port has a network cable connected, the optical port is used for

data switching after the switch restarts.

You can configure a combo port as an electrical or optical port using the combo-port command.
