2. Features
2.1 Features of the AX1240S series(1) Unified lineup Low-end switch provision- The AX1240S series switches, which are low-end Fast Ethernet Layer 2 switches, cover networkedges and provide consistent connectively, operability, and interoperability throughout the AX series.
(2) Robust security
 Authentication and quarantine solutions- Authentication methods such as IEEE 802.1X, Web authentication, and MAC-based authentication
enable individual PCs to be authenticated and placed into a VLAN, while maintaining the freedomof the physical configuration of network edges.
- IEEE 802.1X port-based authentication (static) restricts and releases communicable packets by using
status monitoring, which gives permission for full access communication only to terminals that
conform to a security policy.
- Web authentication by using the RSA SecurID (Note 1) one-time password authentication
functionality can improve network access security. PIN code initial registration and token code
re-entry are also supported (Note 2).
- Devices such as printers can be authenticated by using MAC-based authentication.
- Fixed-IP address terminals also can be authenticated by using the fixed VLAN modes of MAC-based
authentication and Web authentication. Moreover, port trunking allows wireless terminals or similarterminals that have both untagged frames and tagged frames to be authenticated.
- Multistep authentication (Note 3), which performs terminal authentication and user authentication in
two steps, is supported as the network authentication functionality.
 Secure Wake-on-LAN- This functionality allows access to your PC from outside the company, whether you are at home or on
a business trip. You can use a Web browser to access a switch and, via the in-house network, turn on
or off the power to a desktop PC within the company (Note 4).
 Unauthorized DHCP servers and terminals with fixed IP addresses are excluded from networks.
- Robust security measures can be provided via DHCP snooping, which eliminates unauthorized DHCP
servers and terminals with fixed IP addresses.
(Note 1) RSA, the RSA logo, and SecurID are trademarks or registered trademarks of RSA Security Inc. in the United States andother countries.
(Note 2) For this functionality, you must purchase an optional software license separately.
(Note 3) In this authentication, user authentication (IEEE 802.1X or Web authentication) is performed after terminal
authentication (MAC-based authentication) is completed.
(Note 4) For this functionality, you must purchase an optional software license separately.

(3) High reliability for configuring mission-critical networks
 High-quality devices- High reliability through carefully selected parts and strict design and inspection requirements
 Variety of redundant network configurations- High-speed path switchingStandard features such as Autonomous Extensible Ring Protocol (transit nodes), link aggregation(IEEE 802.3ad), and Rapid Spanning Tree Protocol, and proprietary features such as GSRP-aware
allow a redundant high-reliability network to be built. Uplink redundancy, which can build
redundant configurations without using Spanning Tree Protocol, is supported.
- QoS, which gives priority to important packets and audio packets, is supported.
 Layer 2 loop avoidance- The UDLD functionality prevents loops at the spanning tree or frame loss at link aggregation.
- The Layer 2 loop detection functionality detects improperly connected devices on a network, whichhelps prevent loops.

Ver.2.4(4) Support for combo ports and gigabit uplinks
 Gigabit uplink- Two ports can be used simultaneously in combination with 1000BASE-T ports or in combination
with 1000BASE-X (SX, SX2, LX, BX, LH) ports to support various network environments.
(5) Excellent network management, maintenance, and operation
 CFM (Connectivity Fault Management) (Ether OAM)
Continuity checks (CC), loopback, and link traces can perform connectivity monitoring and failuremanagement at the Layer 2 level.
 In addition to the basic MIB-II, many other MIBs, including RMON are supported.
 Improved configuration compatibility with the AX2400S and AX3600S series simplifies the operationof the entire system.
 SD memory cards- Log information storage and software update are supported.
 Console ports are located on the front panel.
 Device cooling system fit for suitable operation (AX1240S-48T2C and AX1240S-24P2C) are adopted.
- The air intake on the side and the air exhaust on the rear reduce the effects of heat vented from otherdevices, and enable stable operation.
(6) Compact design and low environmental impact
 Compact chassis- Compact design with a maximum depth of 35.0 cm and a maximum height of 4.3 cm (1U)
 RoHS is applied, and the environmental impact is reduced.
(7) Fanless design
 Fanless (AX1240S-24T2C)- The number of problems caused due to dust sucked into devices decreases, and a quiet officeenvironment (without noise) is achieved.
(8) Elimination of power cables by PoE
 PoE devices such as IP telephone and wireless LAN AP can be handled (AX1240S-24P2C).
- Because the work of installing power cables is not required, the inconvenience of increasing cables isremoved, the costs for installing power cables are reduced, and the network construction period isshortened.
- PoE (IEEE 802.3af) full power supply (maximum: 369.6 W) allows Class 3 (maximum: 15.4 W)
power-receiving devices to be connected to up to 24 ports. Because PoE Plus (IEEE 802.3at) is also
supported, Class 4 (maximum 30.0 W) power-receiving devices can be connected to up to 12 ports.
(9) IPv6 support
 MLD snooping is supported, which can control the distribution of IPv6 multicast packets.
(10) Precise QoS
 While functioning as Layer 2 switches, the AX1240S series of switches can identify Layer 2 flows,
Layer 3 flows, and Layer 4 flows, and then can control priority and bandwidth. ToS or CoS marking
and mapping are supported, and enable optimal QoS processing and distribution of packets according
to the features of applications such as IP telephone.

Ver.2.4(11) Power saving
 LED operation is controlled in three steps: normal brightness, power saving brightness (operation withlower brightness than normal), and disabled.
- LEDs can be set to blink or turn on in normal brightness when consoles are connected to the switches,
ports are in the link-up state, and SD memory cards are inserted. The settings can be also changed sothat LEDs automatically turn off after operations are completed.
 Port power saving- To achieve power saving, the power to a port is shut off when a link-down state is detected, or whena port is blocked (that is, a port for which the shutdown setting is configured by using
configuration commands) (Note 5).
 Scheduling- The switches can switch automatically to a sleep state, and be woken up from the sleep state, in
accordance with the schedule settings for long holidays, Saturdays, Sundays, public holidays, andevenings.
- The above LED operation and port power saving also can be set up by schedule settings.
(Note 5) The SFP port supports port power saving only when a port is blocked.
