MMAC chassis.

EMM-E6 Installation Guide 2-1

Chapter 2:

Reset Switch

Controls and Indicators

The recessed reset switch re-initializes the EMM-E6 processor. The
activation of this switch will not initialize Non-Volatile Random Access
Memory (NVRAM) where the EMM-E6 stores configuration and
management parameters. The reset switch may be pressed with the point
of a pencil or pen. Once pushed in, the EMM-E6 will re-initialize itself.

LANVIEW LEDs

The EMM-E6 incorporates the LANVIEW status monitoring and
diagnostic system. LANVIEW LEDs can help diagnose many problems,
such as a fault in network cabling. LANVIEW LEDs are identified in
Section 2.3,

EPIM (Ethernet Port Interface Module) Slot

LANVIEW LEDS.

The EPIM slot is a covered opening in the EMM-E6 faceplate that can be
configured with an optional EPIM module.

Serial Ports

The EMM-E6 faceplate provides two serial communications ports for the
connection of out-of-band management devices.

BRIM (Bridge/Router Interface Module) Slots

The BRIM slot is a covered opening in the faceplate that can be
configured with a BRIM module.

2.2 INTERNAL COMPONENTS

The components listed in the following entries are all hidden inside the
MMAC chassis when the EMM-E6 has been installed. These components
may be located by removing the EMM-E6 from the chassis and holding
the module in the orientation shown in Figure 2-2 and Figure 2-3.

Chassis Backplane Connections

The EMM-E6 connects to the backplane buses of the MMAC chassis
through these multipin connectors.

Dip Switch Bank

The EMM-E6 provides a bank of eight dual-position, or “dip” switches.
Several of these switches are used for testing purposes during the
manufacturing process. The dip switches can also be used to clear the
NVRAM of the EMM-E6, which contains configuration and local
management settings, or to force the EMM-E6 to request a new firmware
image from a properly configured BootP server.

BRIM Connectors

The Channel E and Channel F BRIM connectors allow the EMM-E6 to
connect BRIM modules to Ethernet Channels E and F of the EMM-E6.

EMM-E6 Installation Guide 2-3

Chapter 2: Controls and Indicators

EPIM Connector Pins

The EPIM connector pins are two sets of built-in pins that connect the
EMM-E6 Ethernet Channel D to optional EPIM modules. The proper
insertion of the EPIM will automatically connect these pins to the
connector located on the EPIM.

SDRAM SIMM Slot

The EMM-E6 motherboard provides the option of upgrading memory
capacity by using Single In-line Memory Modules (SIMMs).

The EMM-E6 comes with 4 Megabytes (MB) of Shared Dynamic
Random Access Memory (SDRAM) built into the module. The SDRAM
temporarily stores the packets received be the module while forwarding,
filtering, and error checking operations are performed.

2-4 EMM-E6 Installation Guide

Internal Components

LDRAM SIMM Slot

The EMM-E6 comes with 4 MB of Local Dynamic Random Access
Memory (LDRAM) built into the module and one 4 MB SDRAM SIMM,
for a total of 8 MB of Shared Dynamic RAM. LDRAM is the “Main”
memory from which the switching functionality of the EMM-E6 operates.

NOTE

FLASH Memory SIMM Slot

Some advanced EMM-E6 operations, such as extended
RMON or Cabletron Systems Routing Services, require an
EMM-E6 with greater than 8 MB of LDRAM. In these cases, the
4 MB SIMM that is shipped in the LDRAM slot must be
upgraded to a higher-capacity SIMM. Contact your Cabletron
Systems Sales Representative for more information about
available memory upgrades for the EMM-E6.

The EMM-E6 incorporates 2 MB of FLASH Electrically Erasable
Programmable Read Only Memory (FLASH EEPROM). FLASH
memory holds the operating instruction code of the EMM-E6. When the
module is activated, the instruction code (firmware) held in FLASH
memory is forwarded to Main memory, decompressed, and used to start
up the EMM-E6.

The use of FLASH memory, in conjunction with the runtime download
capabilities of the EMM-E6, allows the downloading of firmware to the
module without requiring that the module be shut down. The firmware
download may be performed at any time during the operation of the
module, and the new firmware image will be used at the next reset of the
module.

BRIM-F Ribbon Connector

The BRIM-F ribbon connector provides a connection point for the special
ribbon cable used to connect FDDI BRIMs (the BRIM-F6 or BRIM-F0)
to Ethernet Channel E of the EMM-E6.

The STBY, RCV, XMT, and CLN LEDs are in a matrix, which
provides these indicators for four of the EMM-E6 Ethernet
channels. To read the LEDs, the vertical column indicates the
