AX2500S SeriesCompact gigabit layer2 switches pursuing more high functionality andhigh reliability
The AX2500S series, with its SML (Split Multi Link) function, makes it possible to configure a fault-tolerant network combined with theAX6600S/AX6700S series. The AX2530S-24T is a completely fanless*, high-functionality gigabit layer 2 switch. Further, the AX2530S-24S4X
provides 24 ports for gigabit optic Ethernet and 4 ports for 10 gigabit optic Ethernet, thus making it easier to design large-scale networks incombination with the SML function.
* AX2530S-48T is a semi-fanless switch whose fan activates only when the temperature inside the switch has risen exceeding the permissible level.

High Reliability and High Availability

Fanless Switch (AX2530S-24T, AX2530S-48T)■ SML (Split Multi Link)◎ Enables link aggregation between two different switches.
◎ By using fault-tolerant switches (AX6000S family) together, it becomes possible
to configure a simple redundant network using only link aggregation.

■ Fanless◎ AX2530S-24T is a gigabit switch that is completely fanless.
◎ AX2530S-48T is a semi-fanless switch whose fan activates only when
the temperature inside the switch has risen exceeding the permissible level.
■ Noise suppression◎ Suitable for use in places that should be noise-free (e.g., conference rooms).

【SML function that helps circumvent a line failure】
SML is a function that enables link aggregation between the two different switches,
thus making it possible to continue communications even when a failure has
occurred by taking an alternative route via the counterpart switch.

■ Reduced chance of malfunction◎ Free of failure that may be caused due to dust absorption by the fan.
◎ No physically operable units, thus reducing factors that may cause a failure.

Optic Multiport Switch (AX2530S-24S4X)
FT Switch■ Optic multiport switch capable of large-scale network construction◎ As a distribution switch for enterprise networks, provides 24 ports forgigabit optic Ethernet (this interface is always in high demand).
◎ Provides 4 ports for 10 gigabit interfaces, thus making it possible to allocate anenough bandwidth for uplink connection when using redundancy functions suchas SML or ring protocols.
Link Aggregation

FailureAlternativeRoute■ Use of noise-resistant optic fibers suited to long distance transmission◎ Unlike UTP, optic fibers enable a long distance transmission of 100m or more
(specified that transmission up to 100Km is possible with SFP-LHB).
◎ Supports the SFP+ interface for 10G lines, thus making it easier to configure alow-cost, large line capacity network than with the XFP interface.

Authentication and Security Functions

AX2530S

Link Aggregation■ Triple authentication◎ Mixed use of IEEE802.1X, Web-based authentication and MACauthentication is possible.
■ Multi-step authentication◎ By using two or more authentication methods together, possible to block accessfrom unauthorized terminals and execute user authentication at the same time.

・・・■ Gigabit L2 box switch featuring a largest class of authentication capacity◎ Capable of accommodating up to 1024 authenticated terminals.
■ Stress-free Web authentication◎ Smooth authentication even with advanced cryptosystems (e.g., SSL2048bit)

Green IT and Energy Saving Functions■ L2 Ring Protocol◎ Enables L2 ring configurations using a simple network topology.
■ Prevention of a loop failure◎ Enables loop detection, by which a loop failure that
may be caused accidentally by misconnection can be automaticallyprevented.

■ Dynamic power saving functions that cut unnecessary power consumption◎ Schedule Sleep for automatically powering off the switch during nights andholidays◎ Sleep Cancellation for remotely powering on the switch that has been in thesleep mode
■ Energy saving◎ Energy-saving capability more powerful than that of the AX2400S seriesAX2500S Application Example① A large-scale network with full link aggregation② A floor switch using various authentication/power-saving functions【Point 1 】 Link aggregation between switches
Enables use of a pair of box-type switches equipped with the SML function, as a
distribution switch for which cost efficiency is important.
【Point 2】 Dual-active operation to handle traffic efficiently
Enables effective use of lines through load balancing using link aggregation.

【Point 3】 Simple and stable switching operation
Enables a simple and stable network in which, when a failure has occurred,transmission is continued with the degenerate operation of link aggregation,
thus rendering complicated operations (e.g., route recalculation) unnecessary.

【Point 1】 A wide variety of authentication functions
Enables a secure network configuration even for places where a large numberof people gather irregularly (e.g., conference room).
【Point 2】 Dynamic power-saving functions
Enables powering-off of the switch and link-down of unused ports, according tousage conditions of offices/conference rooms.
【Point 3】 Completely fanless and noise suppressive
AX2530S-24T is a completely fanless switch, therefore noise is suppressed to alevel that does not make people feel uncomfortable even when the switch isplaced nearby.
