I have questions about DECbridge900MX.
(Q.1)
I know that DECbridge900MX has two FDDI ports (A,B) on a front panel.
Can I use the FDDI ports of DECbridge900MX installed in a DEChub900 ?
If I can, is the following configuration right?
**************
* FDDI Ring *
****** ******

Ethernet
DB900MX is connected to FDDI Ring by Physical FDDI ports on a front
panel, and connected to one external Ethernet. And five Ethernet
ports of it were assigned to five Ethernet backplane channels on a
DEChub900. Is it correct?
(Q.2)
Can I assign one FDDI port and six Ethernet ports to DEChub900
backplane channels?
Thanks and Regards,
Kouhei

Q.1) Yes, you can use the FDDI DAS connection in a DEChub 900 and the
configuration you show is exactly the sort of thing it is built to do.
Q.2) You can assign all 6 Ethernets to the backplane (note that each
Ethernet can be _either_ front or back, but not both); whether or not
you will be able to connect just one FDDI to the back is still TBD; as
it stands _now_, you must have either both FDDI front or both back.

Can DECbridge900MX shipped in Jan '94 assign one FDDI to the back? Regards, Kohei | |||||
| 535.4 | IS Dual-Homing Supported at FCS? | HGRNCC::FARADAYCHONG | Faraday Chong@hgo 852-8053590 | Thu Dec 16 1993 02:04 | 8 |
Another config question on DB900MX.
At FCS, can it dual-homed to say DECconcentrator 500?
If this capability is not planned at FCS, when would it be? We need
this to help customer planning their network.

Dual homeing will be supported via the front bezel cabling, but not on
the backplane; so yes - to the DECconcentrator 500 would be ok.
