Reset Switch

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, LANVIEW LEDS.

EPIM (Ethernet Port Interface Module) Slot

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.

2.2INTERNAL 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.
