Glossary
offline state
When the switch is in the offline state, all the installed ports are offline. The ports transmit an
OLS (offline sequence) and they cannot accept a login for connection from an attached device.
Contrast with online state.
OLS
See offline sequence.
online state
When the switch is in the online state, all of the unblocked ports are allowed to login to the
fabric and begin communicating. Devices can connect to the switch if the port is not blocked
and can communicate with another attached device if both devices are in the same zone or if
the default zone is enabled. Contrast with offline state.
Open Systems Management Server
An optional feature that can be enabled on the Director or Edge Switch through the Product
manager application. When enabled, host control and management of the Director or Edge
Switch are provided through an open systems interconnection (OSI) device attached to a
Director or Edge Switch port.
operating state (switch)
The operating states are described as follows:
Online - when the switch is set online, an attached device can log in to the switch if the
port is not blocked. Attached devices can communicate with each other if they are
configured in the same zone.
Offline - when the switch is set offline, all ports are set offline. The switch transmits the
offline sequence (OLS) to attached devices, and the devices cannot log in to the switch.
operating state (port)
Can be beaconing, invalid attachment, link incidents, link resets, no light, not operational,
online, offline, segmented E_Port, port failure, or testing.
operating status (switch)
Can be online, offline, coming online, or going offline.
optical cable
Fiber, multiple fibers, or a fiber bundle in a structure built to meet optical, mechanical, and
environmental specifications. See also jumper cable, optical cable assembly, and trunk cable.
optical cable assembly
Optical cable that is connector-terminated. See also jumper cable and optical cable.
