1112.0. "more questions DecHub900 with 90C" by HITEKS::PEER () Mon Jun 13 1994 21:14

    Now that I can manage the 90C in the DecHub900 are there limitations.
    When I bring up the 90C, I get a screen showing me the meters for 
    collisions, traffic and such. But below those meters (if you will) I
    see N/A. Now I know that I have traffic through those repeater ports
    but I'm not clocking any traffic. Should I be??? What I'm being told
    is that I can't look at the traffic statistics for that module. I can 
    manage the ports on the module, as far as segmenting the port if I 
    choice, but is that the ONLY functionality that I have??
    
    The other question that I have is, if I have (for example) a 900TM
    module attached to the IMB segment in the hub and I power cycle the 
    repeater by disconnecting it from the backplane and plugging it back
    in, I seem to lose my connection to the IMB segment and it defaults
    back to the thinwire segment. Is this the correct behavior for the 
    modules? 
    
    In reference to my first question, I will also have the 90FS modules
    in my hub and I'm now wondering what the limitations as far as managing
    that module will be with Hubwatch.
    
    I would also like the know if there is a manual that discusses the same
    information as the help files within hubwatch. The help files are
    REALLY good, but you need a hub and hubwatch to access them. With
    limited training these days, I would like to be able to read some of
    this information before having to go out to a customer site. The USE
    manuals all point you to the help files. If anyone knows where that can
    be found, I would be extremely helpful. 
    
    My last note 1080, asked for a pointer to the installation and
    configuration manual. I still can not locate them. I still searching.

	The DECrepeater 90C does not provide any statistics, so HUBwatch can't show them to you. I believe that the only functionality you get with this repeater is port status, port enable/disable, and address tracking (and because of some limitations in the way this must be done on the DEChub 900 it needs to have been running a while before the information you get this way is complete). If you pull any module when it is powered up, the MAM will delete backplane configuration associated with that slot.

	...However, the 90FS supports the counters, security and dual port redunadancy so it has all of the managment capabilities of a 900 repeater. Regards, Bob
1112.3	90FS and internal IMB segment	HITEKS::PEER		`Tue Jun 14 1994 22:27`	10
	If the 90FS module has the same functionality as the 900 modules, is it possible for me to connect one of the internal connections on that module to an IMB segment. I noticed that when I view the module that it has both the blue leg and a green leg. If I can pull the green leg down to another IMB segment that would really help. The customer wants the fiber connection bridged from the rest of the network. Regards, Regina

	Regina, You can connect the green leg to either the Thinwire or an IMB segment. An important difference from other IMB-able repeaters is that once you connect the DECrepeater 90FS to an IMB segment, any other DECrepeater 90FS module's green leg can only be placed on that same IMB segment or the Thinwire (as long as the initial 90FS connection remains). The 90FS uses the IMB in the Secretariat backplane. Since there is only one, they must share. Regards, Bob
1112.5	pointer to install/config book	TNPUBS::J_GOLDSTEIN	Run over on the Info Highway	`Wed Jun 15 1994 12:44`	7
	Look for the Install/Config guide in TNPUBS::PUBLIC$DISK:[PUBLIC.ONEHUB]HUBWATCH_WORKSTATIONSV3_INSTALL.PS It's there, I just looked. joan
1112.6	Backplane Questions	HITEKS::PEER		`Wed Jun 15 1994 17:42`	13
	Bob, I'm not sure I understand what the "secretariat backplane". Could you elaborate on that a little more. This is the only 90FS in this hub but I connect that fiber link via another standalone 90FS. I want to be able to bridge that segment. From what I think I'm reading I believe that I won't have any problem...as long as I explain the restrictions, but I think I need to understand it a little better before I can explain it to the customer. Thanks for the input....Regina P.S. If there is a pointer to the information that would be nice!
1112.7	90FS connects to HUB backplane connector called Secretariat	NACAD2::BATTERSBY		`Wed Jun 15 1994 18:10`	8
	What Bob is referring to is that there are two connectors for each backplane slot that are used by the 900 series max modules. The smaller one at the top is the 48 pin Secretariat connector. The other connector is referred to as the 160 pin Matrix connector. The 90FS is one of the smaller modules which only connects to the top connector or Secretariat connector. Bob
1112.8	Don't worry, be happy...	NACAD2::SLAWRENCE		`Thu Jun 16 1994 08:32`	13
	Of the 6 flexible channels used for IMBs by current repeaters, 1 is on the upper (DEChub 90 compatible) connector, and 5 are on the lower connector. A half height module capable of using an IMB can therefor only reach 1. The Hub will allocate that channel to the first IMB that any half height module is connected to. What -.2 was saying was that if you then had another 90FS and tried to connect it to a different IMB, the attempt would fail (because there would not be another available channel that the module could use). It doesn't sound like this applies to you however.

	Thanks for all the help!!! I think I'm on the right track. Regards, Regina
