SERVSWITCH™

4.4.3UPGRADING THE FIRMWARE (FLASH MEMORY)

The ServSwitch has flash memory, which means its firmware may be reloaded (upgraded) in order to support new features or fix any problems in its operation. To get new firmware revisions when they become available, you can download them from our FTP site—at the time of this writing, you would use the “ftp://ftp.blackbox.com/pub/connectivity” directory—or from our Black Box BBS—call (724) 746-7120. For regular -R4 level ServSwitches, filenames will follow these formats: “UPxx.HEX,” where “xx” = the x.x firmware-revision level. Please make sure you get the right file; the ServSwitch will not let you load firmware intended for other Serv models (UxxP.HEX, UxxS.HEX, etc.).

There are two ways to load the firmware into the Switch, as described in the following two subsections.

4.4.3.A Upgrading the Firmware with Terminal-Emulation Software

Take these steps to upgrade the firmware of your ServSwitch with a terminal- emulation program such as ProComm® Plus or Windows HyperTerminal™:

1.Connect one of your computer’s or terminal’s serial ports to the Switch’s RS-232 port as described in Section 4.4.1.

2.Run your terminal-emulation program and set it to use the serial port that’s connected to the Switch (COM1:, COM2:, etc.) in “direct connect” mode. Set its serial-communication parameters to 9600 bps, 8 data bits, no parity, and 1 stop bit (“9600,8,N,1”).

3.Make sure the ServSwitch is turned OFF, then turn it ON while holding in both the “” and “” buttons (the “+” and “–” buttons on the 2-port unit) on the Switch’s front panel. Once the Switch has powered up, release the next port/previous port buttons, then the power button. The Switch should light LED 1 and send you the message:

Waiting for file at 9600 baud

If you want to download the new firmware file at 57,600 bps instead, change your terminal emulator’s data-rate setting to 57,600 bps, 8 data bits, no parity, and 1 stop bit (“57600,8,N,1”), then press the Switch’s “” or “+” button again. The Switch should light LED 4 and send the message:

Waiting for file at 57,600 baud

(If you need to switch back to 9600 bps, change the terminal-emulator settings back, then press the Switch’s “” or “–” button.)

4.Use the terminal program’s “send text file” or “upload” function to send the new firmware file to the Switch, using the same protocol you would to send an

SW725A-R4, SW722A-R4, SW723A-R4, KV3108SA-R4, SW724A-R4 specifications

The Black Box SW721A-R4, SW724A-R4, KV3108SA-R4, SW723A-R4, and SW722A-R4 are cutting-edge network switches that cater to the demanding needs of modern data environments. These models are designed to provide high performance, reliability, and advanced features suitable for both enterprise-level deployments and smaller networks.

The SW721A-R4 and SW724A-R4 are primarily layer 2 switches that support essential networking protocols such as IEEE 802.1Q for VLAN tagging, ensuring secure and efficient traffic management. With robust forwarding capabilities, these switches boast high-speed Gigabit Ethernet ports, which enable seamless data transfer and reduce latency in data-driven applications. Their fanless design also ensures quiet operation, making them ideal for office settings and noise-sensitive areas.

Another noteworthy addition is the KV3108SA-R4, a versatile KVM switch that provides remote management capabilities. This model can control multiple servers and computers from a single console, allowing IT personnel to streamline operations and reduce physical space requirements. With support for high-resolution video output and an intuitive user interface, the KV3108SA-R4 enhances usability while maintaining efficiency in server management.

The SW723A-R4 and SW722A-R4 models further enhance network capabilities with their advanced Layer 3 functions. These switches support static routing and dynamic routing protocols, making them suitable for complex networking scenarios. They are equipped with a comprehensive set of security features, including port security and access control lists (ACLs), ensuring that sensitive information is well-protected against unauthorized access.

All of these Black Box models operate on advanced technologies such as QoS (Quality of Service), which helps prioritize critical traffic and ensures optimal performance during peak usage periods. Additionally, they support Power over Ethernet (PoE), enabling the powering of network devices such as IP cameras and VoIP phones without the need for additional electrical outlets.

In summary, the Black Box SW721A-R4, SW724A-R4, KV3108SA-R4, SW723A-R4, and SW722A-R4 represent a fusion of performance, versatility, and security in network infrastructure. These switches are perfect for businesses looking to enhance their connectivity solutions, ensuring that they can meet the demands of an increasingly digital world while maintaining high standards of efficiency and reliability.
