CAUTION: Alerts you to a potential hazard that could cause loss of data, or damage the system or equipment.
WARNING: Alerts you to a potential hazard that could cause personal injury.
Safety Instructions
CAUTION: Circuit devices are sensitive to static electricity, which can damage their delicate electronics. Dry weather conditions or
walking across a carpeted floor may cause you to acquire a static electrical charge.
To protect your device, always:
• Touch the metal chassis of your computer to ground the static electrical charge before you pick up the circuit device.
• Pick up the device by holding it on the left and right edges only.
• If you need to connect an outdoor device to the switch with cable, then you need to add an arrestor on the cable between the
outdoor device and this switch.
NOTE: The switch is an indoor device; if it will be used in outdoor environment or connect with an outdoor device, use a lightning
arrestor to protect the switch.
Do not place the product outdoors in a sandstorm.
Before installation, make sure input power supply and product specifications are compatible with each other.
To reduce the risk of electric shock, disconnect all AC or DC power cords and RPS cables to completely remove power from the unit.
Before importing/exporting configuration, make sure the firmware version is updated.
After a firmware upgrade, the switch will reset the configuration automatically to the latest firmware version.

Chapter 2: Overview
2. Overview
2.1 Introduction
The 24 + 4 or 48 + 4 Managed Gigabit Switches with 4 SFP+ 10G are easy-to-implement managed Ethernet switches. Models have 24 or 48 ports of Gigabit Ethernet connectivity plus four 10G ports. These switches deliver more intelligent features to improve the availability of your critical business applications, protect your sensitive information, and optimize your network band­width to deliver information and applications more effectively. Both switches support advanced security management capabilities and network features including data, voice, security, and wireless technologies. These switches are easy to deploy and configure, providing stable and quality performance network services. Typical applications include small business and enterprise.
2.2 Features
• Performs wire-speed, non-blocking switching to enable wire-speed transport of multiple packets at low latency on all ports
simultaneously.
• Provides full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.
• Uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received
into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
• You can also manage the switch over the network with a Web browser or Telnet application. Manage it in-band using SNMP or
RMON (Groups 1, 2, 3, 9) protocols. Configure and monitor the switch out-of-band via a null-modem serial cable. (See Appendix C for wiring options.)

Chapter 4: Making Network Connections
4. Making Network Connections
4.1 Connecting Network Devices
You can connect the switch to 10-, 100-, or 1000-Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers.
Twisted-pair devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e, or 6 cable for 1000BASE-T connections, or Category 5 or better for 100BASE-TX connections.
4.2 Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
See Appendix C for further information on cabling.
CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform to FCC standards.
4.3 Connecting to PCs, Servers, Hubs, and Switches
STEP 1: Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
Figure 4-1. Making twisted-pair connections.
STEP 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See Section 7.4: Network Wiring Connections in the Network Administrator’s Installation and Getting Started Guide.) Otherwise, attach the other end to an available port on the switch.
Make sure each twisted-pair cable does not exceed 100 meters (328 ft.) in length.
NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise,
backpressure jamming signals might degrade overall performance for the segment attached to the hub.
STEP 3: As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or amber (100 Mbps) to indicate that the connection is valid.

Chapter 5: System Configuration
Parameter Description
Group Name: The name identifying the privilege group. In most cases, a privilege level group consists of a single module (for
example, LACP, SMTP or QoS), but a few of them contain more than one. The following description defines these privilege level groups in details:
System: Contact, Name, Location, Timezone, Log.
Security: Authentication, System Access Management, Port (contains Dot1x port, MAC based and the MAC Address Limit), ACL,
HTTPS, SSH, ARP inspection and IP source guard.
IP: Everything except “ping.”
Ports: Everything except “VeriPHY.”
Diagnostics: “ping” and “VeriPHY.”
Maintenance: System Reboot, System Restore Default, System Password, Configuration Save, Configuration Load, and Firmware
Load.
Web: Users, Privilege Levels and everything in Maintenance.
Privilege Levels: Every group has an authorization privilege level for the following subgroups: configuration read-only,
configuration/execute read-write, status/statistics read-only, status/statistics read-write (e.g. for clearing of statistics). User privilege should be same or greater than the authorization privilege level to have the access to that group.
5.4 IP
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an internet network.
IP is a “best effort” system, which means that no packet of information sent over is sure to reach its destination in the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices connected to the extended network.
The current version of the Internet protocol is IPv4, which has 32-bit IP addresses allowing for more than four billion unique addresses. This number is reduced drastically by the practice of webmasters taking addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which would have 128-bit IP addresses. This number can be represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the protocol of choice for most of the Internet.
5.4.1 IPv4
The IPv4 address for the switch could be obtained via DHCP server for VLAN 1. To manually configure an address, you need to change the switch's default settings to values that are compatible with your network. You may also need to establish a default gateway between the switch and management stations that exist on another network segment.
Configure the switch-managed IP information in the screen shown in Figure 5-8.
The “Configured” column is used to view or change the IP configuration.
The “Current” column is used to show the active IP configuration.
Web Interface
To configure an IP address in the Web interface:
1. Click “System,” “IP Configuration.”
2. Specify the IPv4 settings, and enable DNS proxy service if required.
3. Click “Save.”

Chapter 5: System Configuration
Figure 5-9. The IPv6 Configuration screen.
Parameter Description
Auto Configuration: Enable IPv6 auto-configuration by checking this box. If this fails, the configured IPv6 address is zero. The
router may delay responding to a router solicitation for a few seconds, so the total time needed to complete auto-configuration can be significantly longer.
Address: Provide the IPv6 address of this switch. IPv6 address is in 128-bit records represented as eight fields of up to four hexadecimal digits with a colon separating each field (:). For example, “fe80::215:c5ff:fe03:4dc7.” The symbol “::” is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can only appear once. It can also represent a legally valid IPv4 address. For example, “::192.1.2.34.”
Prefix: Provide the IPv6 prefix of this switch. The allowed range is 1 to 128.
Gateway: Provide the IPv6 gateway address of this switch. IPv6 address is in 128-bit records represented as eight fields of up to
four hexadecimal digits with a colon separating each field (:). For example, “fe80::215:c5ff:fe03:4dc7'.” The symbol “::” is a special syntax that can be used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it can only appear once. It can also represent a legally valid IPv4 address. For example, “::192.1.2.34.”
5.5 Syslog
The Syslog is a standard for logging program messages. It allows separation of the software that generates messages from the system that stores them and the software that reports and analyzes them. It can be used for general information, analysis, and debugging messages. It is supported by a wide variety of devices and receivers across multiple platforms.

Parameter Description
Server Mode: Indicates the server mode operation. When the mode operation is enabled, the syslog message will be sent out to
the syslog server. The syslog protocol is based on UDP communication and received on UDP Port 514. The syslog server will not send acknowledgments back to the sender since UDP is a connectionless protocol and it does not provide acknowledgments. The syslog packet will always be sent out even if the syslog server does not exist. Possible modes are:
Enabled: Enable server mode operation.
Disabled: Disable server mode operation.
Server Address 1 and 2: Indicates the IPv4 host addresses of syslog server 1 and server 2 (for redundancy). If the switch provides DNS feature, it also can be a host name.
Syslog Level: Indicate what kind of message will be sent to syslog server. Possible modes are:
Info: Send information, warnings, and errors.
Warning: Send warnings, and errors.
Error: Send errors.
