Re: IBM 8228 MAU
The 8 ports on the 8228 are electro-mechanical. The Ring-In, Ring-Out ports are not. The thingy with the red light has a 9-volt battery in it. It is used to reset the 8 ports. Insert the thingy into the port until the light turns on then off (takes only a couple of seconds. You need to do this to an 8228 any time you have not used it for awhile.

RE: IBM 8228 MAU
Has anyone ever seen a schematic diagram for the "port resetting thingy" ? I have a MAU that does not seem to work... Perhaps all it needs is a "reset" with such a device... Perhaps one could build such a device yourself...

RE: IBM 8228 MAU
Bob, The item you refer to is called a Ring Initialization tool. Try calling IBM. I searched Black Box, Google.com and IBM's website and found nothing. Someone at IBM has one though. Call tech services and ask where you can order one. -Original Message- From: Bob Johnson [mailto:[EMAIL PROTECTED]] Sent: Monday, April 02, 2001 4:06 PM To: 'Jim Barksdale'; [EMAIL PROTECTED] Subject: RE: IBM 8228 MAU Has anyone ever seen a schematic diagram for the "port resetting thingy" ?

Re: IBM 8228 MAU
Please correct me if i am wrong here, but isn't it required to connect RI to RO to form the ring ? I always kept them connected together when using the MAU in a lab environment. To test the ports i can only agree to ElephantChild's method. Greetings Reinhold On Sun, 1 Apr 2001, ElephantChild wrote: On Sat, 31 Mar 2001, John Chang wrote: I have a IBM 8228 MAU.

To test all ports except RI and RO, first connect a machine to port 1 and have it insert into the ring, then connect another to each of ports 2-8 in turn, each time having it insert and checking that the machines see each other. To test RI and RO, you need 2 trunking cables. Connect the 2 MAUs together, then connect the 2nd machine to ports 1-8 of MAU 2 and repeat the insert-and-check test as above. Then, with 1 machine connected to each MAU, test RI by disconnecting first one end, then the other, then both, each time checking that the machines see each other. Reconnect RI and check RO the same way. Warning: If any test fails, it could be the MAU port, the machine, or the cable. Use known good cables and machines to the extent possible. -- According to Joyce Melton, "respondability" is cromulent. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: IBM 8228 MAU Question
Cabling for the 2504: http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2501/ 2500ug/pin.htm Cabling for the 2521: http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2520/ 2520_23/c2520cab.htm You can to connect the Token Ring ports to a custom DB9 (like the one used for a DB9 console connection to the back of your serial port, but wired differently), and then a straight-through cable to my IBM 8228 MAU which has RJ-45 jacks. At least that's the way the one in my lab is, but I inherited this gear and didn't have to figure it all out (at least not yet). Also they could be connected via the serial ports via a DTE/DCE cable between the serial ports. -- Jason Roysdon, CCNP+Security/CCDP, MCSE, CNA, Network+, A+ List email: [EMAIL PROTECTED] Homepage: http://jason.artoo.net/ Cisco resources: http://r2cisco.artoo.net/ ""Vincent"" [EMAIL PROTECTED] wrote in message 94j8bh$qvr$[EMAIL PROTECTED]">news:94j8bh$qvr$[EMAIL PROTECTED]... Hi; Currently, I orderd a IBM 8228 MAU and a media filter, not yet arrived. 1) What else do I need to connect my Cisco 2504 (DB9) and Cisco 2521 (Support UTP, STP)? Any special cable that I need? 2) Is this possibe for a "Type 1DB9 9 (male) to UTP cable" connect from the MAU to cisco 2504?
