Outra maneira de identificar esse problema é observar a variável de bootloader STACK 1+1 com o uso do comando set no modo bootloader. Para colocar o switch no modo bootloader, clique no botão mode enquanto o switch inicia a inicialização.
switch: set
ABNORMAL_RESET_COUNT=0
AUTOREBOOT_RESTORE=1
BOARDID=20569
BOOT=flash:packages.conf
BSI=0
MAC_ADDR=00:ab:cd:ef:01
MANUAL_BOOT=yes
MODEL_NUM=C9300-48UXM
MODEL_REVISION_NUM=D0
MOTHERBOARD_ASSEMBLY_NUM=73-17959-06
MOTHERBOARD_REVISION_NUM=A0
MOTHERBOARD_SERIAL_NUM=XXXXXXXXXXX
RANDOM_NUM=1901228755
RET_2_RCALTS=

switch:
Solução
Desmarque a variável Stack 1+1. Depois que o switch conseguir inicializar normalmente.
switch:unset STACK_1_1
switch: set
ABNORMAL_RESET_COUNT=0
AUTOREBOOT_RESTORE=1
BOARDID=20569
BOOT=flash:packages.conf
BSI=0
MAC_ADDR=00:ab:cd:ef:01
MANUAL_BOOT=yes
MODEL_NUM=C9300-48UXM
MODEL_REVISION_NUM=D0
MOTHERBOARD_ASSEMBLY_NUM=73-17959-06
MOTHERBOARD_REVISION_NUM=A0
MOTHERBOARD_SERIAL_NUM=XXXXXXXXXXX
RANDOM_NUM=1901228755
RET_2_RCALTS=
ROMMON_AUTOBOOT_ATTEMPT=3
SWITCH_IGNORE_STARTUP_CFG=1
SWITCH_NUMBER=2
SYSTEM_SERIAL_NUM=XXXXXXXXXX
TEMPLATE=access
VERSION_ID=V01
switch:
Quando a variável do carregador de inicialização Stack 1+1 estiver desconfigurada, emita o comando boot para que o switch possa inicializar a partir da variável de inicialização definida no switch.
switch: boot
