Glossary
event code
A three-digit numeric code that displays in the event log and identifies a specific event that
occurred. This code provides information on system failures, such as hardware failures; failure
locations; or general information on normal system events.
event log
Record of significant events that have occurred at the director or switch or through the HAFM
Management Services application, such as FRU failures, degraded operation, and port
problems.
EWS
(EWS) — Web-based interface that allows administrators or operators with a browser-capable
PC and Internet connection to monitor and manage a director. The interface provides a GUI
similar to the Element Manager application and supports director configuration, statistics
monitoring, and basic operation.
EWS interface timeout
If the embedded web server interface is running but no user activity occurs, (such as viewing
different pages, refreshing, or reconfiguring information), the application times out after 30
minutes. The user must log in again. A login dialog box displays if the user attempts to access
any pages after the timeout has occurred.
EWS interface window
The window for the embedded web server interface. The window is divided into two separate
panels: the navigation panel on the left, and the main panel on the right.
exchange
A term that refers to one of the Fibre Channel protocol "building blocks," composed of one or
more nonconcurrent sequences.
expansion port
(E_Port) — Physical interface on a Fibre Channel switch within a fabric that attaches to an
expansion port (E_Port) on another Fibre Channel switch to form a multiswitch fabric. See also
segmented E_Port.
explicit fabric login
Data field size, supported by an F_Port, that is agreed upon during fabric login.
extended distance feature
XDF. A means to extend the propagation distance of a fiber-optic signal.
fabric
Fibre Channel entity that interconnects node ports (N_Ports) and is capable of routing
(switching) Fibre Channel frames using the destination ID information in the Fibre Channel
frame header accompanying the frames.
