If Trap function is required, remember to enable Trap (use "snmp-server enable
traps" command). and remember to properly configure the target host IP address
and community string for Trap (use "snmp-server host" command) to ensure Trap

command).

2.5 Switch Upgrade

ES4626/ES4650 switch provides two ways for switch upgrade: BootROM upgrade
and the TFTP/FTP upgrade under Shell.

2.5.1 Switch System Files

The system files includes system image file and boot file. The updating of the switch
is to update the two files by overwrite the old files with the new ones.
The system image files refers to the compressed files of the switch hardware drivers,
and software support program, etc, namely what we usually call the IMG update file. The
IMG file can only be saved in the FLASH with a defined name of nos.img
The boot file is for initiating the switch, namely what we usually call the ROM update
file ((It can be compressed into IMG file if it is of large size). The boot file can only be
saved in the ROM in which the file name is defined as boot.rom
The update method of the system image file and the boot file is the same. The
switch supplies the user with two modes of updating: 1. BootROM mode; 2. TFTP and
FTP update at Shell mode. This two update method will be explained in details in
following two sections.
