SANbox2-16 Fibre Channel Switch
Installation Guide
Q
Expansion Port
See E_Port.
ExtCredit
Allows full speed operation over distances
greater than 10 kilometers. Additional
credit buffers are borrowed from other
ports (which must be set to donor state).
Decimal value 0-65535
Fabric Management Switch
The switch through which the fabric is
managed.
Fabric Name
User defined name associated with the file
that contains user list data for the fabric.
Fan Fail LED
An LED that indicates that a cooling fan in
the switch is operating below standard.
FC-PLDA
Fibre Channel Private Loop Direct Attach
Flash Memory
Memory on the switch that contains the
chassis control firmware.
Frame
Data unit consisting of a start-of-frame
(SOF) delimiter, header, data payload,
CRC, and an end-of-frame (EOF)
delimiter.
FRU
Field Replaceable Unit
Heartbeat LED
A chassis LED that indicates the status of
the internal switch processor and the
results of the Power-On Self-Test.
Initiator
The device that initiates a data exchange
with a target device.
In-Order-Delivery
A feature that requires that frames be
received in the same order in which they
were sent.
Input Power LED
A chassis LED that indicates that the
switch logic circuitry is receiving proper DC
voltages.
InteropCredit
This variable determines the number of
credits we will advertise on an ISL. Older
versions of software required that we
match their offering. (decimal value,
0-255)
IP
Internet Protocol
ISLSecurity
ISLSecurity determines which switches a
port will establish a link with. ANY - we will
link with any switch. Ours - we will only link
to another QLogic switch. None - the port
will not establish an ISL link.
LCFEnable
LCFEable gives preference to Link control
frames (such as class 2 ACK frames) over
other frames, when queued for
transmission in the switch. This may
provide better performance when running
Class 2 traffic. LCFEable is incompatible
with MFSEnable, and both cannot be
selected. (True / False)
LIP
Loop Initialization Primitive sequence
