FDDI SmartSwitch Modules
The FDDI SmartSwitch Module (9F310-02,
9F426-02 and 9F426-03) connects two external
FDDI networks to a high speed switching
backplane, the INB. The external FDDI networks
connect to the FDDI SmartSwitch Module using
standard FDDI Dual Attached Station (DAS) A/B
ports.
The FDDI SmartSwitch Modules operate in two
modes: as Bridging or as a SecureFast Switch
(SFS). The FDDI SmartSwitch Modules are able to
accept variable-size LAN packets, translate them
into a generic form for transmission to other front
panel ports, and segment them into fixed length
data blocks for time division multiplexed
transmission over the INB backplane to other
Fast Packet Switched based modules.
FDDI Switch Module
The FDDI Switch Module (9F116-01) is a two-port
FDDI bridge used to connect an external FDDI
network with one of the two FDDI networks, FNB
1 or FNB 2; or to connect between FNB 1 and FNB
2 on the FNB backplane. The external FDDI
network connects to the FDDI Switch Module
using a Dual Attached Station (DAS) interface via
standard FDDI Medium Interface Connectors
(MIC) on the front panel.
FDDI MicroLAN Modules
The FDDI MicroLAN Modules are a family of
concentrators providing eight or twelve master
ports for connections to a Single or Dual Attached
Station. Modules attach directly to the
SmartSwitch 9000 FNB.
The following devices of FDDI MicroLAN Modules
are supported:
• The 9F120-08 is an eight-port FDDI dual
channel concentrator via MMF MIC with dual
FNB attachments.
• The 9F122-12 is a twelve-port FDDI dual
channel concentrator via UTP RJ-45 with
dual FNB attachments.
• The 9F125-08 is an eight-port FDDI dual
channel concentrator via SMF MIC with dual
FNB attachments.
• The 9F241-12 is a twelve-port FDDI dual
channel concentrator via MMF SC with FDDI
bandwidth statistics and dual FNB
attachments with dual MAC.
