824.0. "GIGASWITCH/ATM and MODULAR UTP LINE CARD PROBLEM?" by SOS6::HOFFMANN (HOFFMANN Lionel/loc=evt/DTN number=858 5647) Wed Feb 12 1997 14:07

Hello,

    I have installed a gigaswitch/ATM running version V2.0 more precisely:

    _CMM version 1.80
    _QLCV15 and QLCV20 line cards version V2.0

    I had two line cards : _an old type QLCV15 optical (4 mmf non modular
    ports)
                           _And a new one QLCV20 , a modular one

    Some questions :

    1)Each card works fine separately into the gigaswitch and becomes the
    master one.But it is impossible to get both at the same time because of
    hardware incompatibility.Can someone confirm that point?is it normal?

    2)The final configuration must use the modular card with UTP PMD's.
    I had to setup LANE between one UTP port of the modular line card and a
    sun machine with an ATM/SBUS adapter but I got problems....

    The Physical link has never become up between the two devices .
    I'm sure of the cable because I'tried different straight cables as it
    is normally.......

    So Of course I could'nt get the LAN ok because no link up...
    I have tried UNI version 3.0 and 3.1 but the same.......

    So did I forget anything? Is there any specific setup for the line card?
    It seems ok with the Clock menu because it is recognized as a 
    QUAD LINE card V2.0...and the upper led is green
    But the port is seen as "NOT CONNECTED" and into a "TEST" state
    Did I miss some points?


    3)Normally,I must configure also a VNSWITCH on a second UTP port of the
     modular line card.Does somedy know if it is ok with version V1.0-106 for
    using a UTP PMD within the VNSWITCH which is the same normally that used 
    
    with the gigaswitch utp modular line card???(DAGGU-AA is the part
    number)

	Any help appreciated

You should be able to mix linecards just fine. I do it all the time with my test switch in the lab. Make sure that both line cards are running the same firmware version -- we don't support mixing and matching firmware versions.

NOT CONNECTED is an ILMI address registration state that could be caused either by no physical connection or by some ILMI/UNI problem. If you have ... A SONET STS-1 UTP mod-PHY Try toggling the port between SONET and SDH mode. If you have the mode set to one value on the GS/ATM, and another on the Sun, it won't work! An E3/T3 mod-PHY Try configuring different line type settings in SNMP. An E1 mod-PHY Check with engineering to see if it is one of the "old" models that can only support PLCP mode.
824.3	Wrong firmware or wrong cable	NOTED::defctb.lkg.dec.com::Bill	Bill Melaragni, HPN, DTN 226-6670	`Thu Feb 13 1997 07:54`	19
	There are one of two likely problems with this config: 1) The verion of the line card code does not support the UTP modPHY 2) You have the wrong cable. For the first case, you'll need to do this simple test: remove the UTP modPHY card and re-insert it. If the code supports this PHY card, the two LEDs on the front of the PHY card will blink green three times within one second. If the LEDs do NOT blink, you have an old version of code and you need to upgrade it. If the LEDs do blink then you likely have the wrong kind of cable. You may need a cross-over cable, not straight thru. The modPHY installation manual details the pinout of the UTP card. Compare this to the pinout of the SUN adapter card. bill
824.4	Upgrade to latest code	NPSS::ROUNDS		`Thu Feb 13 1997 10:20`	3
	Before you do anything, I suggest you upgrade to the latest firmware versions. Clock code is at 1.8.2. Then, at least you know you are running the latest and greatest code. Then start working any problems.
824.5	AGAIN...PROBLEM IS THERE	SOS6::HOFFMANN	HOFFMANN Lionel/loc=evt/DTN number=858 5647	`Fri Feb 14 1997 09:13`	21
	Hello, Thank you everybody for your help but I have always the problem and it is becoming critical on the customer site....... does somedy already installed that type of module? I have installed a OPTICAL PMD within the module and IT WORKS. Only the UTP PMD's don't work....but I am sure the firmware is ok because when i plug into one utp pmd ,the two upper leds blink three times....... About the cable ,I have built a new cable with the rigt pinout ... It is ok ...except if it is different on digital products... The problem is critical because this sun machine works on a FORE SWITCH using UTP links........ Any ideas. any experience? Who is responsible at the engineering side of such a module?I need URGENT informations ....... regards LIonel
824.6	pinout again	NOTED::defctb.lkg.dec.com::Bill	Bill Melaragni, HPN, DTN 226-6670	`Mon Feb 17 1997 08:00`	16
	>>About the cable ,I have built a new cable with the rigt pinout ... >>It is ok ...except if it is different on digital products... Well, you may still have the wrong pinout. The Forum provides for DCE and DTE pinouts of the MJ connector. We have choosen to make the modPHY an "ATM Network Equipment" device. The pinout is: 1 RX+ 2 RX- 7 TX+ 8 TX- Pins 3,4,5,6 are tied to chassis via a capacitor. bill
824.7	Thank you bill	SOS6::HOFFMANN	HOFFMANN Lionel/loc=evt/DTN number=858 5647	`Tue Feb 18 1997 09:35`	13
	Thank you bill .Everything is ok now with the pinout. In addition to this,I could see thet The version was 2.0 but a Field Test one .I have Upgraded with the last one ( Firmware code 300 ) and now it works.I did'nt see immediately that it was wrong because when I I plugged the UTP PMD ,The upper leds flashed Three times...... But now it is OK I have another problem of LANE EMULATION now with a sun machine but it is another story..(See next entries..if you have any ideas) Best regards Lionel
