Console Management
When placed in the managed chassis such as 2-slot CH02M chassis, this
card can be locally managed by connecting a simple serial terminal such as
a notebook computer that has an RS232 port or via a commonly available
USB to RS232 adapter. In Windows XP, HyperTerminal™ is an application
available for emulating a serial terminal. You can also search for TeraTerm
or PuTTY which are free alternatives, especially if the operating system is
Vista or Win7.
Settings
Baud Rate: 38,400 / Data bits: 8 / Parity bits: none / Stop bits: 1
Handshaking: none / Emulation: VT-100
Default Username: admin / Default Password: admin
Connect the serial cable to the CH02M's DB9. Run the terminal emulation
program. With power on, press [ESC] or [Enter] to display the "Main Menu"
screen. The following is an example.

The upper side of the console screen displays QSFP+ transceiver status
and the current state of each QSFP+ including DDM, TX Fault status, LOS,
CDR Lock. The bottom side of the console screen provides options to set
up the device such as LFP, loopback test. See below for detailed
explanations of provided options:
Operation
Select any of the menu items by keying in the menu item number or letter.
Use the [ESC] to return to a previous menu. Any setting is immediately
applied to the transponder's circuitry. After all of the parameter settings
have been selected, press "s" from the main menu to save the parameters
in non-volatile RAM (NVR). To revert to previous settings before saving,
press "r" to reset (reload previously saved parameters).
Explanation of Settings:
<1> Port Active: This will enable or disable the card. When inactive, no
transmissions will be able to occur.
<
2> Data Rate: This is the data rate of QSFP+ module. Currently, it is fixed
at 10GE or 10.3125Gbps.
<3> Fiber Configuration: This will enable users to enable or disable Link
Fault Pass-Through function and read the serial data stored in QSFP+
modules when QSFP+ transceivers are inserted.
<4> Loopback Test Function: Select QSFP+ loopback function.
<R> Device Reset: This will cause the parameters settings in NVR to be
reloaded.
<D> Set to Default: Restore all saved settings to factory default settings.
<S> Store Parameters: Saves the setting parameters into non-volatile
RAM (NVR)
<U> Update with X-Modem: Update firmware via X-Modem.
<P> Password Setup: Enter this menu to change the login password. The
old password must be keyed in followed by the new password twice. If the
password is ever forgotten, please contact customer support for details on
resetting the password.

Fiber Configuration
<1> Link Fault Pass-Through: Use this menu item to enable or disable the
"QSFP" LFP function.
Link Fault Pass-through or LFP is a method of forwarding a link loss from
one media to the other over the transponder. LFP function of FRM220-40G-
2Q supports 4 links (λ) of QSFP1+ and QSFP2+ fiber link fault application
for troubleshooting purposes.
For example:
As shown in the figure above, when "QSFP1+ Link 1" LFP is enabled
(QSFP1+1 LFP Enabled) and a fault occurs on the QSFP1+ fiber link 1, the
transponder would pass that fault to the QSFP2+ link 1 port. This would
force the link down on the QSFP2+ link 1. A check of the FRM220-40G-2Q
transponder would reveal the fiber link loss and corrective action could be
performed.
