Port TX reset timer Specifies the duration, in tenths of seconds, a port’s transmitter is
turned off when re-patching a port without first un-patching it. The
port repatches with its transmitter off. Then, after the specified
time elapses, the transmitter turns back on.
This setting is required in environments where ports are not
always unpatched before repatching. It primarily affects end
devices that require a certain amount of time for the transmitter to
turn off before the link is forced to renegotiate which in turn
guarantees that new devices will be recognized.
I
NTELLA P ATCH switches can patch ports as quickly as 100µs, often
resulting in devices not recognizing that a change in the physical
layer occurred, and therefore not renegotiating new devices.
Instead, the old devices are still recognized even though they are
no longer physically attached.
0.0 (Default) Transmitter is always on during port patching and
un-patching.
0.1–4.0
Specifies the duration, in tenths of seconds, that the
transmitter is turned off when re-patching previously
connected ports. Select a value long enough to satisfy the
protocol specification for forcing a link to renegotiate.
TX fault correction Determines action taken when transceiver faults are detected:
Some SFP transceivers support the MSA laser eye safety circuit
specification. Many conditions can trigger the laser eye safety
circuit, including high laser power, high laser bias current, high or
low voltage, and high or low temperature.
Unchecked (default): If the laser eye safety circuit is
triggered, the transmitter turns off.
If you select this option, turning a transmitter back on
requires manual intervention: physically unplugging the fiber
optic cable, re-seating it, re-seating the SFP transceiver, and
then power-cycling the blade or chassis.
Checked: The I
NTELLA P ATCH switch actively monitors the
transceivers, checking SFPs for a fault every five seconds.
If a fault is detected, the laser eye safety circuit is reset
which turns the transmitter back on. If the condition that
caused the failure is still present, the fault is triggered again
and the transmitter may potentially stay off until the condition
is corrected.
Copper Ethernet Blades
(ACI-2059-E16-2 /
ACI-2059-S15-2)
Options in this section specify behavior for Copper Ethernet
blades.
Always negotiate Specifies rate negotiation with other copper Ethernet devices:
Checked (default): The switch automatically negotiates with
other copper Ethernet devices. A
PCON recommends that you
do not change this setting without first contacting support.
For contact information, see
Contacting A PCON on page 4.
Unchecked: The switch does not negotiate with other copper
Ethernet devices.
