Introduction
The 9F116-01 MicroLAN™ Module (shown in Figure 1-1) is a two port FDDI
bridge/router used to connect an external FDDI network to one of the two FNB
networks, FNB-1 or FNB-2, on the SmartSwitch 9000 FNB backplane. Another
configuration option allows the module to bridge/route between FNB-1 and
FNB-2 on the FNB backplane. The external FDDI network connects to the 9F116-
01 using a DualAttached Station (DAS) interface on the module’s front panel. The
9F116-01 is ANSI X3T9.5-compliant with two instances of Station Management
(SMT), two instances of MAC, and four instances of PHY and PMD (two per
interface).
Features
Processor
The 9F116-01 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides a platform for all management functions within a
scalable RISC-based architecture.
System Management
The 9F116-01 interfaces to the two System Management Buses (SMB-1 and
SMB-10) for intermodule management. Management features include the
following:
• Module Insert/Bypass Control
• MAC Placement
• Station Management (SMT) Statistics
• Bridging Statistics (for all interfaces) including
- Frames Filtered
- Frames Forwarded
- All STA Parameters
Hardware Bridging Logic
Hardware frame filter/forward logic increases the bridging performance of the
9F116-01, allowing the module to achieve higher throughputs (up to 50,000
packets per second).

Introduction
1-2
SpanningTree Algorithm
The 9F116-01 supports both IEEE 802.1d and DEC Spanning TreeAlgorithm (STA)
protocols.
Connectivity
The 9F116-01 provides one FDDI dual attached connector pair from the module
front panel. This connector pair allows the 9F116-01 to act as a DAS (with two
FPIMs installed) or a SAS (with one FPIM) on the SmartSwitch 9000 FNB. The
9F116-01 has three physical FDDI interfaces (front panel, FNB-1, and FNB-2) and
allows bridging between any two of them.
FPIMs
The 9F116-01 uses FDDI Port Interface Modules (FPIMs) to provide several media
options on the front panel interfaces. These FPIMs are available in various media
types including the following:
• Multimode Fiber Optic (FDDI MIC)
• Single Mode Fiber Optic (FDDI MIC)
• Unshielded Twisted Pair (RJ-45)
• Shielded Twisted Pair (RJ-45)
LANVIEW LEDs
The 9F116-01 uses LANVIEW: the Cabletron Systems built-in visual diagnostic
and status monitoring system. With LANVIEW LEDs, you can quickly identify
the device, port, and physical layer status at a glance.
Hot Swapping
The 9F116-01 can be installed or removed from the chassis while the SmartSwitch
9000 is powered up without affecting the operation of the rest of the network.

Installing the MicroLAN Modules
SmartSwitch 9000 MicroLAN Modules can be installed in any of the 14 slots that
are available. To install, follow the steps below:
1. Remove the blank panel, covering the slot in which the MicroLAN Module
will be installed. All other slots must remain covered to ensure proper airflow
and cooling.
2. Unpack the MicroLAN Module by carefully removing it from the shipping
box. (Save the box and packing materials in the event the module must be
reshipped.)
3. Attach one end of the ESD wrist strap packaged with the SmartSwitch 9000
chassis to your wrist. Plug the other end into the ESD Wrist Strap Grounding
receptacle in the lower right corner of the SmartSwitch 9000 Chassis shown in
Figure 2-1.
4. Remove the MicroLAN Module from the plastic bag. (Save the bag in the
event the module must be reshipped.) Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).
5. Examine the MicroLAN Module, carefully checking for damage. If any
damage exists, DO NOT install the module. Immediately contact Cabletron
Systems Technical Support.
6. Install the MicroLAN Module in the chassis by sliding it in any available slot
and locking down the top and bottom plastic tabs, as shown in Figure 2-1.
Take care that each module slides in straight and properly engages the
backplane connectors. When installing a module, ensure that the circuit card
is between the card guides, as shown in Figure 2-1. Check both the upper and
lower tracks.

The Reset Switch
The Reset switch is located on the front panel, under the top plastic tab as shown
in Figure 2-2. It serves two functions:
• Pressing the Reset switch twice within three seconds causes the processor
(i960) to reset.
• Pressing and holding the switch on for three or more seconds causes the
moduletoshutdown. Pressingandholding againfor threeseconds restarts the
module.
SNMP management may be used to disable this switch to enhance module
security.

The module uses NVRAM to store user-
entered parameters such as IP addresses,
device name, etc. To reset these parameters to
the factory defaults, toggle this switch. Once
reset you can use the defaults or enter new
parameters, which are stored in NVRAM
when the module is powered down, and
remain there until the switch is toggled again.
