Chapter 1. IBM Flex System FC3171 8 Gb SAN Switch - QLogic

Frame
Data unit consisting of a start-of-frame (SOF)
delimiter, header, data payload, CRC, and an
end-of-frame (EOF) delimiter.
Hard Zone
Hard zoning divides the fabric for purposes of
controlling discovery and inbound traffic.
Inactive Firmware
The firmware image on the switch that is not in
use.
In-band Management
The ability to manage a switch through another
switch over an inter-switch link.
Initiator
The device that initiates a data exchange with a
target device.
Inter-Switch Link
The connection between two switches using
E_Ports.
LIP
Loop Initialization Primitive sequence
Logged-in LED
A port LED that indicates device login or loop
initialization status.
Management Information Base
A set of guidelines and definitions for SNMP
functions.
Management Workstation
PC workstation that manages the fabric
through the fabric management switch.
Mesh Topology
A fabric in which each chassis has at least one
port directly connected to each other chassis in
the fabric.
MIB
Management Information Base
Multistage Topology
A fabric in which two or more edge switches
connect to one or more core switches.
NL_Port
Node Loop Port. A Fibre Channel device port
that supports arbitrated loop protocol.
N_Port
Node Port. A Fibre Channel device port in a
point-to-point or fabric connection.
OK LED
A switch LED that indicates that the switch
logic circuitry is receiving proper DC voltages.
Orphan Zone Set
Zones that are currently not in a zone set are
considered to be part of the orphan zone set.
The orphan zone set is not an actual zone set,
but rather a way of displaying the zones that
are not currently in a zone set.
Pending Firmware
The firmware image that will be activated upon
the next switch reset.
POST
Power On Self Test
Power On Self Test (POST)
Diagnostics that the switch chassis performs at
start up.
Principal Switch
The switch in the fabric that manages domain
ID assignments.
QuickTools
Switch management web applet.
SFP
Small Form-Factor Pluggable.
Small Form-Factor Pluggable
A transceiver device, smaller than a GigaBit
Interface Converter, that plugs into the Fibre
Channel port.
SNMP
Simple Network Management Protocol
Soft Zone
Soft zoning divides the fabric for purposes of
controlling discovery. Members of the same
soft zone automatically discover and communicate
freely with all other members of the
same zone.
Switch Fault LED
A switch LED that indicates the status of the
internal switch processor and the results of the
Power On Self Test.
