IBM SAN32M1, Installation And Service Manual

15 Chapter 1: General information
• Switch or management server failure (hardware or software).
• Ethernet LAN communication failure between the switch and
management server
• Link failure between a port and attached device.
• ISL failure or segmentation of an E_port.
Fault isolation and service procedures vary depending on the system
event information provided. Fault isolation and related service
information is provided through maintenance analysis procedures
(MAPs) documented in Chapter 3. MAPs consist of step-by-step
procedures that prompt service personnel for information or describe
a specific action to be performed. MAPs provide information to
interpret system event information, isolate a switch failure to a single
FRU, remove and replace the failed FRU, and verify switch operation.
The fault isolation process normally begins with Map 000.
Ensure the correct switch is selected for service (if the management
server manages multiple switches or other IBM products) by enabling
unit beaconing at the failed switch. The amber system error (ERR)
LED on the switch front panel blinks when beaconing is enabled.
Instructions to enable beaconing are incorporated into MAP steps.
Remote workstation configurations
Using a standard web browser, the SAN Management application
and Element Manager applications can be downloaded and installed
on remote user workstations that are LAN-attached to the
management server.
Operators at these workstations can manage and monitor switches
controlled by the management server. A maximum of five concurrent
users (including a local user) can log in to the SAN Management
application.
Each remote workstation must have access to the LAN segment on
which the management server is installed. Switch administrative
functions are accessed through the LAN and management server. The
LAN interface can be:
• Part of the dedicated 10/100 Mbps LAN segment that provides
access to managed switches. This switch-to-management server
LAN connection is part of the equipment installation and is
required. Connection of remote workstations can be through the
