2438.0. "900EE disconnected but works???" by MOSCOW::FELIZHANKO () Wed Jun 28 1995 12:33

Could anybody explain the following:
	
- DEChub 900MS
- DECswitch 900EE:
	some servers are sitting on a thinwire - AUI Ports 1 and 6 (don't ask 
	me why)
- DECrepeater 900TM:
	a lot of clients on its ports

Nobody has touched neither 900EE nor 900TM (that means 900TM is on the ThinWire
Ethernet, 900EE is disconnected from a backplane and works for front panel
ports). HUBwatch shows that (at least LAN Interconnect window and 900EE port
configurator).
Nevertheless, everybody are happy. The clients talk to the servers. HUBwatch
shows activity on port 2 (green, fwding enable, % filtered > 0 etc). Port 2 LED
on a front panel is green but nothing is connected to the port physically.
Looks like port 2 is assigned to the ThinWire Ethernet on a backplane by God
or artificial intelligence.
When I try to turn port 2 to a backplane by HUBwatch it returns "SNMP response
format/parse error" and nothing changes.
Reset to factory settings for both 900EE and DEChub doesn't help. 
Well, it works and let him. But what all that means?

    There are two LEDs for port #2. Are they both green? Or is the
    right-hand LED amber, and is it flashing with traffic?
    Did you just upgrade anything? Did you try refreshing the Hubwatch main
    screen & then refresh the lan interconnect window?
    
    What happens when you pop the latch (hot-swap the module)?
    FW versions might be helpful.

2438.2900EE is just fine but...MOSCOW::FELIZHANKOThu Jun 29 1995 07:4615
	Mike,

	Both port 2 LEDs on the 900EE look just fine for normal work with
	forwarding/filtering: left-hand LED is steady green, right-hand one
	is amber and flashing with traffic.
	All the modules in the hub and Hub Mngr itself are at latest FW 
	versions (DEChub - V4.0.0, 900EE - V1.1.0, HUBwatch - V4.0)
	Refreshing screens? No changes at all. HUBwatch is stubborn and
	shows that the 900EE is still disconnected from a backplane Ethernet,
	all ports out but actually it IS connected and works just fine...
	I can't hot-swap the 900EE at the moment because I'm talking about
	live network in our office. May be this night...

2438.3Try reset currentCONSLT::BUZZELLThu Jun 29 1995 12:528
    
    
         Before you swap the 900EE try resetting the hub manager to current
    setttings then restart HUBwatch. I have seen instances of the MAM
    knowing what was really going on but not returning the correct info to
    HUBwatch until after a reset to current.
