SAPPHIRE : SML-24GE4C

Sapphire SML-24GE4C is a managed L2 industrial Ethernet switch providing 24 Gigabit RJ45 Ethernet and 4 Gigabit SFP/RJ-45
combo ports ports. It supports abundant L2 features such as VLAN STP/RSTP/MSTP ERPS QoS ACL and supports Web/CLI
management and third-party SNMP management. It has an IP40 protection class and meets EMC industrial level 4 requirements. The
switch supports a wide power input voltage range of AC and 48-57VDC and a wide operating temperature range of -40 to +80°C. In
addition to its compact size for space-saving installation, each product has passed a 100% burn-in test at 80°C to ensure its quality
high-reliability Transmission. All of these features make the product ideal for applications that require high-reliability
transmission such as video surveillance tolling systems ITS and factory automation.

Applications:
The SML-24GE4C supports redundant ring technology and features strong rapid self-recovery capability to prevent interruptions
and external intrusions. It incorporates advanced ERPS (Ethernet Ring Protection Switching) technology, Spanning Tree Protocol
(802.1s MSTP), and redundant power input system into the customer's industrial automation network to enhance system reliability and uptime in harsh factory environments. In certain simple Ring networks, the recovery time of data link can be as fast as 20ms.
With IP40 aluminum industrial case protection, the SML-24GE4C provides a high level of immunity against electromagnetic
interference and heavy electrical surges which are usually found on plant floors or in curb side traffic control cabinets. It also
possesses an integrated power supply source with wide range of voltages (48 to 57V DC) for worldwide high availability
applications requiring dual or backup power inputs. Being able to operate under the temperature range from -40 to 80 degrees C,
the SML-24GE4C can be placed in almost any difficult environment.
