Page 17: Chapter 1. Introduction
Chapter 1. Introduction The IBM SAN Fibre Channel Switch 2109 Model S16 is a 16-port, fibre-channel, switch. The IBM 2109 Model S16 Switch consists of a system board with connectors for supporting up to 16 ports, and a fabric operating system for creating and managing a fabric.
Page 18: Performance
F frames when the output port is free. Manageability The unit is managed using the 10BASE-T Ethernet port for Telnet or Web-based management using the IBM StorWatch Specialist. The switch also provides a front operator panel for simple switch configuration and diagnostics. System components The system board is enclosed in an air-cooled chassis that is either mounted in a standard rack or used as a stand-alone unit.

Page 59 7. If it is not possible or appropriate to access the switch in this fashion, replace the short cable. If it is an IBM-approved cable, ask the customer to replace it. If you are dealing with a long cable or one where both ends cannot be accessed at the switch, you need to have the cable installer test the cable.

In order to manage a switch, you must have access to one of the available management methods. Telnet, SNMP, and IBM StorWatch Specialist require that the switch be accessible using a network connection. The network connection can be from the switch Ethernet port (out of band) or from fibre channel (in band).
Page 86: Hardware Setup For Switch Management
To enable remote connection to the switch, the switch must have a valid IP address. Two IP addresses can be set; one for the external out-of-band Ethernet port and one for in-band fibre channel network access. IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide...

Page 93: Generic Traps
Generic traps Setting up the switch SNMP connection to an existing managed network allows the network system administrator to receive the following generic traps. coldStart indicates that the agent has reinitialized itself such that the agent configuration might be altered. This also indicates that the switch has restarted.
Page 94: Managing Using The Management Server
Because the management server is accessed using its well-known address, an application can access management information with a minimal knowledge of the existing configuration. An application accesses one well-known place to obtain management information about the entire fabric. IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide...
Page 95: Using The Management Server
The fabric topology view exposes the internal configuration of a fabric for management purposes. It contains interconnect information about switches and devices connected to the fabric. Under normal optional circumstances, a device (typically an FCP initiator) queries the name server for storage devices within its member zones. Because this limited view is not always sufficient, the management server provides the management application with a management view of the name server database.

Page 98: Power-On Self-Test (Post)
When the switch is started, a series of commands are executed to test the switch. This procedure is called the POST. The fabric OS POST includes the following tests: ramTest - Bit write and read test of SDRAMS in the switch. IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide...

A semi-custom switching power supply, that is repackaged for the requirements of the switch enclosure architecture, is used.

Attention: This command cannot be executed on an operational switch. Before using the camTest command, disable the switch using the switchDisable command. Related error messages: DIAG-CAMINIT, DIAG-CAMSID, DIAG-XMIT centralmemorytest Table 30 shows the centralMemoryTest command which verifies that the central memory in each loom ASIC is functioning correctly by checking the following: v The built-in-self-repair (BISR) circuit in each loom chip does not report a failure to repair bad cells (bisr test).

Page 113 Table 32. cmiTest example Synopsis cmiTest [passCount] Availability Administrator Description Use this command to verify that the multiplexed 4-bit control message interface (CMI) point-to-point connection between two ASICs is functioning properly. Also use it to verify that a message with a bad checksum sets the error and interrupt status bits of the destination ASIC and that a message with a good checksum does not set an error or interrupt bit in any ASIC.

Page 120 Note: Make sure that you reset GBIC mode before returning the machine to the customer. The GBIC mode is activated by executing the following command before executing the crossPortTest command: IBM SAN Fibre Channel Switch: 2109 Model S16 Installation and Service Guide...
Page 121 sw:admin> setGbicMode 1 When activated, only ports with GBICs installed are included in the crossPortTest list of ports to test. For example, if only ports 0 and 3 have GBICs installed and the GBIC mode is activated, crossPortTest limits its testing solely to ports 0 and 3.
