Page 11: Introduction
The GBX24 incorporates advanced management software allowing guaranteed bandwidth per port or per VLAN. Port aggregation allows multiple ports to act as a single trunk, or provides redundant ports for reliability within your network. The Gigabit switch uses store‐and‐forward switching architecture that filters and forwards data after the complete data packet is received and examined to be free of errors. Front panel LEDs allow for easy recognition of the switch operation status and for troubleshooting. All Gigabit ports support both full and half duplex operation, which can provide up to 2000 Mbps of bandwidth to the connected devices, with auto‐negotiation providing the capability to connect to 10/100/1000 Mbps network devices. The GBX24 also supports back‐pressure and IEEE 802.3x advanced flow control capability, which can reduce congestion and prevent packet loss. In addition, all ports support the MDI/MDI‐X auto‐detect function. This allows connection of any device (including embedded Ethernet adapters and Switches/Hubs) to the port of this switch using the regular cable, with the RJ‐45 port auto‐detecting and auto‐switching to MDI/MDI‐X mode without requiring an uplink port or cross‐over cable. The GBX24 is fully integrated and provides management software. As standard, the GBX24 incorporates Built‐In‐Test (BIT), which provides extensive and configurable testing of the GBX24 hardware. The GBX24 provides maximum throughput and flexibility for demanding networks, with all the layer 3 features you expect. The rugged GBX24 is ideal as a backbone for a gigabit server or as the robust core of a demanding, all‐gigabit network. The GBX24 layer 3/4 managed Gigabit switch provides both layer 2 and layer 3 switching functionality. Its high‐performance design offers a comprehensive set of features: • Switching: Port trunking, broadcast storm protection, extensive VLAN support, IGMP snooping, Rapid Spanning Tree and link aggregation • Quality of Service: DiffServ and bandwidth provisioning The GBX24 is available in a range of build styles, from Level 1 (Standard), suitable for a benign office‐like environment, right through to Level 5 (Rugged Conduction‐ cooled), capable of withstanding the harshest of environments.

Page 16: Identifying Your Board
2.2 Identifying Your Board The GBX24 is identified by labels at strategic positions. These can be cross‐checked against the Advice Note provided with your delivery. Identification labels, similar to the example shown in Figure 2‐2, attached to the shipping box and the antistatic bag give identical information: GBX24 product code, product description, equipment number and board revision. Figure 2-2 Product Label (Packaging) On the board within the antistatic bag, there is an identifying label similar to the example shown in Figure 2‐3 attached to the PCB. Figure 2-3 Product Label (Product) On conduction‐cooled versions of the board (build levels 4 and 5), there is also a label similar to the example shown in Figure 2‐4 attached to the front panel. Figure 2-4 Product Label (Conduction-cooled Product) See the Product Code Information section in Appendix A for more details on the product code (GBX24‐xxxxx). 16 GBX24 VME 24 Port Gigabit Ethernet Switch Publication No. GBX24-0HH/2... -

Page 19: Installation And Power Up
The GBX24 may require up to 9 A from a 5 V power supply within VMEbus Specification limits (+5 V +5 % ‐2.5 %). The ±12 V supply lines (VMEbus ±12 V +5 % ‐2.5 %) are not used. CAUTION Do not operate the GBX24 on an extender card. The GBX24 paddle card uses differential pair impedance matched tracking that is not found on typical extender cards. 4.1 Board Installation Notes 1.

Page 20: Connecting To Gbx24
4.2 Connecting to GBX24 The GBX24 is factory configured to provide Gigabit Ethernet switching straight out of the box. As with other Ethernet devices, connections can be made and broken as required while the system is operational. Full software configuration is possible; however this is not necessary for proving initial operation. NOTE Full functionality is only possible after the GBX24 has been fully booted-up. Apart from providing switch ports, the GBX24 also has two COM ports for direct switch access, and an out‐of‐band Ethernet service port. 4.2.1 Serial Connection to a Terminal/HyperTerminal (COM1/2) The GBX24 has two EIA232 COM ports, both of which are configured as DTE. The ports are used for the following purposes: COM1 Management Software Command Line interface and BIT interface. COM2 BIT fail interface (not required during normal operation). The ports are configured to 9600 baud, 8 bits/character, 1 stop bit and no parity, which should be reflected in the terminal/terminal emulation software, together with VT100 mode and flow control off. Since the COM ports are Tx/Rx only, any handshaking options should also be turned off. COM1/COM2 are available on P2 ... -
