Cabletron Systems EMM-E6 - Manual (Page 24)

Chapter 3: Installation
3-4 EMM-E6 Installation Guide
Switch definitions are as follows:
• Switch 1: Cabletron Systems use only.
• Switch 2: Cabletron Systems use only.
• Switch 3: Not Used.
• Switch 4: Not Used.
• Switch 5: Cabletron Systems use only.
• Switch 6: Forced Download. Changing the state of this switch
(i.e., moving the switch from one position to another) forces a BootP
download.
After changing the position of Switch 6 and restarting the EMM-E6,
the EMM-E6 requests a new image download until it either receives a
new image or the reset button on the front panel is pressed. When the
reset button is pressed, the EMM-E6 continues trying to contact a
BootP server, but will timeout in approximately one minute. If the
EMM-E6 times out, the image is loaded from its FLASH memory.
• Switch 7: NVRAM Reset. The EMM-E6 uses NVRAM to store
user-entered parameters such as IP addresses, device name, etc.
Changing the state of this switch (i.e., moving the switch from one
position to another) resets these parameters to the factory defaults.
NOTE
Do NOT change the state of Switch 6 unless you have a station
acting as a BootP server for the EMM-E6. This BootP station
must reference a station that is acting as a TFTP (Trivial File
Transfer Protocol) server and that contains the EMM-E6 image
file. The EMM-E6 will request the location of the image file from
the BootP server and use TFTP to download that file from the
TFTP server.
If one of these requirements is not met, the EMM-E6 Forced
Download operation will not be completed correctly.
