1 Introduction This chapter introduces the 2H252-25R SmartSwitch 2200 device and provides information about how to obtain additional support from Enterasys Networks. Important Notice Depending on the firmware version used in the 2H252-25R, some features described in this document may not be supported. Refer to the Release Notes shipped with the 2H258-17R to determine which features are supported. 1.
Overview The 2H252-25R is used to connect individual high-bandwidth user devices, such as workstations, or to provide a central switching point for multiple 100-Mbps Fast Ethernet segments. The optional HSIMs provide high speed uplinks to networking technologies such as Fast Ethernet, Gigabit Ethernet, Fiber Distributed Data Interface (FDDI), Wide Area Network (WAN), and Asynchronous Transfer Mode (ATM). Some HSIMs can provide additional Fast Ethernet ports in varying media types.
Overview The RAD requests start at an interval of 1 per second. The interval then doubles after every transmission until an interval of 300 seconds is reached. At this point, the interval remains at 300 seconds. The RAD requests continue until an IP address is received from a RARP or BootP server, or an IP address is entered using Local Management. NOTE: The 2H252-25R will reboot after RAD is successful. 1.1.
Overview 1.1.5 Remote Monitoring (RMON) The 2H252-25R supports all nine Ethernet RMON groups. The Statistics, Alarms, Events and History groups are enabled on all ports by default. Enterasys Networks RMON Actions is a vendor-specific extension of RMON and provides the ability to set an “Action” on any SNMP MIB variable. The Action can be triggered by any RMON Event and/or Alarm. An example of an Action would be to turn off a MIB-2 interface if a broadcast threshold is crossed. 1.1.
Overview Administrators can configure up to four rate limit rules per port; however, each rule must not include conflicting 802.1p priority values. In order to control traffic inbound and outbound on the same port, two rate limit rules must be configured (one inbound and one outbound). Since the rate limiting operation occurs after the processing of the multi-layer classification rules, the two features can be combined to provide application-aware rate limiting.
Overview 1.1.11 802.1 Port Priority The 802.1 port priority is used to assign a default priority to the frames received without priority information in their tag header, map prioritized frames to the appropriate transmit queues, and prioritize frames according to protocol type. The 802.1 port priority is part of the IEEE 802.1D standard. 1.1.12 Management Management of the 2H252-25R is accomplished using SNMP compliant management tools for in-band Local Management.
Overview 1.1.15 Standards Compatibility The 2H252-25R is fully compliant with the IEEE 802.3, 802.3u, 802.3x, 802.1D, and 802.1Q standards. The 2H252-25R provides IEEE 802.1D Spanning Tree Algorithm (STA) support to enhance the overall reliability of the network and protect against “loop” conditions. The 2H252-25R supports a wide variety of industry standard MIBs including RFC 1213 (MIB II), RFC 1757 (RMON), RFC 1493 (Bridge MIB), RFC 1354 (FIB MIB), and RFC 1190 (Path MTU Discovery).

2 Network Requirements Before installing the 2H252-25R, review the requirements and specifications referred to in this chapter concerning the following: • SmartTrunk (Section 2.1) • 10BASE-T Twisted Pair Network (Section 2.2) • 100BASE-TX Twisted Pair Network (Section 2.3) The network installation must meet the requirements to ensure satisfactory performance of this equipment. Failure to do so will produce poor network performance.
100BASE-TX Network 2.3 100BASE-TX NETWORK The fixed ports (ports 1 through 24) of the 2H252-25R provide an RJ45 connection that supports Category 5 UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u 100BASE-TX Fast Ethernet network requirements for the devices to operate at 100 Mbps. Refer to the Enterasys Networks Cabling Guide for details. NOTE: The fixed ports of the 2H252-25R support Category 5 UTP cabling that has an impedance between 85 and 111 ohms.
3 Installation ELECTRICAL HAZARD: Only qualified personnel should install the 2H252-25R. NOTE: Read the Release Notes shipped with the device to check for any exceptions to the supported features and operation documented in this guide. This chapter provides the instructions required to install the 2H252-25R. A Phillips screwdriver is required to install options into the device or install the device into a rack.

The 2H252-25R is now ready to be configured through Local Management.
4 Troubleshooting This chapter provides information concerning the following: • Using LANVIEW (Section 4.1) • Troubleshooting Checklist (Section 4.2) • Using the RESET Button (Section 4.3) 4.1 USING LANVIEW The 2H252-25R uses Enterasys Networks’ built-in visual diagnostic and status monitoring system called LANVIEW. The LANVIEW LEDs (Figure 4-1) allow quick observation of the network status to aid in diagnosing network problems.

Setting the Mode Switches B.3 SETTING THE MODE SWITCHES Figure B-2 shows the location of the mode switches and the switch settings for normal operation. These switches are set at the factory and rarely need to be changed. Switch definitions and positions are as follows: • Switches 1 through 4 – For Enterasys Networks use only. • Switch 5 – COM Port Autobaud. The default (OFF) position enables Autobaud sensing on the COM port for Local Management sessions.
Setting the Mode Switches • Switch 6 – Forced BootP. NOTE: After changing the position of switch 6, DO NOT reapply power to the chassis until there is a station on the network acting as a BootP server, which contains the downloadable firmware image file. DO NOT attempt a Forced BootP unless a BootP server has been configured for the 2H252-25R. The BootP server references the location of a station acting as a Trivial File Transfer Protocol (TFTP) server containing the 2H252-25R image file.
SIMM Upgrade B.4 SIMM UPGRADE Memory upgrade is available for the 2H252-25R to expand its DRAM to 32 MB. This section explains how to locate and add/replace a Single In-line Memory Module (SIMM). For information on the available SIMM upgrades, call Enterasys Networks for technical support. For details on getting help, refer to Section 1.2. B.4.1 Locating SIMMs Figure B-3 shows the two locations of the DRAM SIMM connector.
SIMM Upgrade B.4.2 Installing the DRAM SIMM CAUTION: Observe all antistatic precautions when handling sensitive electronic equipment. To install a DRAM SIMM, refer to Figure B-4 and proceed as follows: 1. With the SIMM alignment notch oriented as shown in Figure B-4, insert the SIMM down between the connector teeth. 2. Pivot the SIMM downward so the connector clips align with the two side notches of the SIMM and the connector clips lock the SIMM into place.
Installing Optional HSIM or VHSIM Interface Modules B.5 INSTALLING OPTIONAL HSIM OR VHSIM INTERFACE MODULES Figure B-5 shows the location of the two connectors for an optional High HSIM or VHSIM. Depending on the HSIM or VHSIM installed, one or both connectors are used. NOTE: The installation instructions for the optional HSIM or VHSIM are in the associated user’s guide.
