E_D_TOV

See error-detect time-out value.

Embedded Web Server

Administrators or operators with a browser-capable PC and an Internet connection can monitor and manage the director through an Embedded Web Server interface. The interface provides a GUI similar to the Product Manager application, and supports director configuration, statistics monitoring, and basic operation.

error detect time out value

E_D_TOV defines the time the switch waits for an expected response before declaring an error condition.

error message

Indication that an error has been detected. See also information message and warning message.

Ethernet

A widely implemented local area network (LAN) protocol that uses a bus or star topology and served as the basis for the IEEE 802.3 standard, which specifies the physical and software layers. Baseband LAN allows multiple station access to the transmission medium at will without prior coordination and which avoids or resolves contention.

Ethernet hub

A device used to connect the HAFM server and the directors it manages.

event code

Code that provides the operator with information concerning events.

event log

Record of significant events that have occurred on the director, such as FRU failures, degraded operation, and port problems.

expansion 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 multi-switch fabric. See also segmented E_Port.

explicit fabric login

Data field size, supported by an F_Port, that is agreed upon during fabric login.

fabric

Entity that interconnects 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.
