The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set, and does not allow any user adjustment. Class 1 Laser transceivers comply with the following safety standards:

• 21 CFR 1040.10 and 1040.11 U.S. Department of Health and Human Services (FDA).

• IEC Publication 825 (International Electrotechnical Commission).

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization).

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered hazardous.

Safety Information

CLASS 1 LASER TRANSCEIVERS

Laser Radiation and Connectors

Notice

When the connector is in place, all laser radiation remains within the ﬁber. The maximum amount of radiant power exiting the ﬁber (under normal conditions) is -12.6 dBm or 55 x 10 watts.

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

Introduction

The 9H423-28 (Figure 1-1) is a switching module with twenty-four 10 Mbps Ethernet ports and four 100 Mbs Fast Ethernet ports. The module is conﬁgured with two RJ21 connectors, two RJ45 connectors, two ST ﬁber connectors and a slot for an FEPIM. The two RJ21 connectors provide twenty-four 10 Mbps Ethernet ports. The RJ45 connectors, ST connectors and FEPIM (the module supports either the FE-100TX or the FE-100FX) provide the four 100 Mbps Ethernet ports. The two ST connectors represent a single port, as one connector is for transmit and one is for receive. Each module also provides an additional port that connects directly to the Internal Network Bus (INB) backplane interface. This module uses a SmartSwitch ASIC design and an advanced Intel i960 microprocessor provides a platform for all management functions within a scalable RISC-Based Architecture.

microprocessor. This

This module can operate in two modes: either as a 28-port Ethernet traditional switch (using 802.1d standards) with a high speed backbone connection, or as a Secure Fast Switch (SFS) with 28 Ethernet connections. Each port can be conﬁgured to operate in the Full Duplex mode. This conﬁguration allows each 10BASE-T port to provide a full 20 Mbps of bandwidth and the 100BASE-T ports to provide 200 Mbps of bandwidth. The ﬁber ports on this module operate only in Full Duplex mode.

Network management information is available through a variety of methods. All information based on Simple Network Management Protocol (SNMP) is accessible either via an in-band (Front Panel port), Side Band (SMB-10), or via the Environmental Module’s COM ports. Serial Line Internet Protocol (SLIP) or Point-to-Point Protocol (PPP) is supported by the Environmental Module’s COM ports. For more information on the SMB-10, SLIP, or PPP, refer to the

9000 Local Management User’s Guide.

The 9H423-28 also features front panel LANVIEW™ Diagnostic LED’s to offer ata-glance status information about each front panel port, as well as the operation of the overall module.

Introduction

Features

Processor

The 9H423-28 module is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions, such as Spanning Tree, RMON, and MIB support, within a scalable RISC-Based architecture.

Fast Packet Switching

The 9H423-28 module incorporates a hardware-based switch design referr ed to as the SmartSwitch ASIC, a collection of custom ASICs designed speciﬁcally for high-speed switching. Because all frame translation, address lookups, and forwarding decisions are performed in hardware, these modules can obtain a throughput performance of greater than 750K pps.

Management

The 9H423-28 features SNMP for local and remote management. Local management is provided through the RS-232 COM ports on the SmartSwitch 9000 Environmental Module, using a standard VT -220

terminal or emulator . Remote management is possible through Cabletron’s SPECTRUM or any SNMPcompliant management tool. Included as management features are the IETF Standard Management Information Base (MIBs) RMON (RFC1271), IETF MIB II (RFC-1213), IETF Bridge MIB (RFC-1493), and a host of other Cabletron enterprise MIBs. These modules also offer a wide variety of statistical network management information to enhance network planning and troubleshooting. The 9H423-28 provides information for each front panel Ethernet port, including packet counts along with errored frame information, such as collisions, CRCs, and Giants, via a variety of industry standard and private MIBS. Industry-standard IEEE 802.1d bridging, including Spanning Tree Algorithm, is supported.

Connectivity

The 9H423-28 module has one interface to the INB and 28 front port connections. The INB interface is a ﬁxed connection to INB-B that allows the module to communicate with other SmartSwitch 9000 modules supporting various LAN technologies including: Token Ring, FDDI, Ethernet, WAN, Fast Ethernet and ATM. The module is conﬁgured with two RJ21 connectors, two RJ45 connectors, two ST ﬁber connectors and a slot for an FEPIM. The two RJ21 connectors provide twenty-four 10 Mbps Ethernet ports, and the RJ45 connectors, ST connectors and FEPIM (the module supports either the FE-100TX or the FE-100FX) provide four 100 Mbps Ethernet ports. The multimode ST connectors provide a 100BASE-FL connection, with links up to 2000 meters in length.

1-2

Auto-negotiation

The auto-negotiation feature (available only with the 100BASE-T RJ45 ports ) allows the module to automatically use the fastest rate supported by the device at the other end (either 10 Mbps or 100 Mbps at either half or full duplex). To

NOTE

Introduction

negotiate duplex, both the 9H423-28 and the attached device must be conﬁgured for auto-negotiation. If only the 9H423-28 is conﬁgured for auto-negotiation, the module will set the connection to half duplex at either the 10 Mbps or 100 Mbps rate. This technology is similar to how modems negotiate transmission speed, ﬁnding the highest transmission rate possible. Similarly, auto-negotiation determines the highest common speed between two devices and communicates at that speed. If no common speed is detected, the device will be partitioned.

All RJ45 connections are capable of auto-negotiation, and can operate at 10 Mbps or 100 Mbps, full or half duplex. Fiber connections can only operate at the 100 Mbps rate, full or half duplex.

Standard Ethernet/Full Duplex Operation

The 9H423-28 module supports both 100BASE and 10BASE technology. This allows each port on the module to be conﬁgured, through local and or remote management (SNMP), to operate in standard Ethernet mode (simplex) or full duplex mode. Operating in standard Ethernet mode limits bandwidth to 10 Mbps/100Mbps per port, while operating in duplex mode doubles bandwidth from 10 Mbps/100Mbps to 20 Mbps/200 Mbps per port.

NOTE

Management Information Base (MIB) Support

The 9H423-28 module provides MIB support including:

• RMON (RFC-1271)

• IETF MIB II (RFC-1213)

• IETF Bridge MIB (RFC-1493) and a host of other Cabletron Enterprise MIBs.

For a complete list of supported MIBs, refer to the release notes provided with the 9H423-28.

INB

The 9H423-28 module attaches to INB-B of the SmartSwitch 9000 Backplane. The INB Backplane is designed to transport ﬁxed length data blocks between modules in the SmartSwitch 9000 using an INB Time Division Multiplexing (ITDM) design. The SmartSwitch 9000 INB bus delivers 2.5 Gbps of true data bandwidth with all control and management communication being serviced on the 8-bit out-of-band bus. The time slices of the INB manager operates in all three modes at once, without user intervention.

1-3

Introduction

Arbitration for the backplane is accomplished in the INB Time Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensures that no one can get the backplane for more than one time slice at a time.

The ITDM RAM contains 256 4-bit locations. This RAM is used to hold slot numbers of modules participating in INB backplane arbitration. The arbitration engine accesses this RAM once every time slice to get a slot number. That slot number will be granted access on the next time slice if it is requesting. The arbitration engine is always one time slice ahead, meaning that the value read from the RAM is for the next time slice, not the current time slice.

LANVIEW LEDs

The 9H423-28 module uses LANVIEW – the Cabletron Systems built-in visual diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly identify, at a glance, system status as well as the device, port, and physical layer status. Two LEDs indicate the transmission and reception of data from the INB SmartSwitch 9000 backplane connection. Each of the 12 Ethernet front panel ports features two LEDs per port to indicate the port’s Administrative status (enabled/ disabled), LINK status (Link/Nolink), and Data Activity (receiving and transmitting data).
