Specifying the Boot Up Order for I/O modules
Specifying the Boot Up Order for I/O modules
By default, the NAM and I/O modules in the I/O module slots boot up in the order of their chassis slot
numbers (that is, modules in the lower numbered slots boot up before the modules in the higher
numbered slots). To reverse that boot up sequence, use the hardware module boot-order reverse
command. To use the default boot up sequence, use the no hardware module boot-order reverse
command.
SUMMARY STEPS
1. config t
2. [no] hardware module boot-order reverse
DETAILED STEPS
Table 8-6 Module States
show module Command
Status Output Description
powered up
The hardware has electrical power. When the hardware is powered up, the
software begins booting.
testing
The switching module has established connection with the supervisor and the
switching module is performing bootup diagnostics.
initializing
The diagnostics have completed successfully and the configuration is being
downloaded.
failure
The switch detects a switching module failure upon initialization and
automatically attempts to power-cycle the module three times. After the third
attempt, the module powers down.
ok
The switch is ready to be configured.
power-denied
The switch detects insufficient power for a switching module to power up.
active
This module is the active supervisor module and the switch is ready to be
configured.
HA-standby
The HA switchover mechanism is enabled on the standby supervisor module.
Command Purpose
Step 1
config t
Example:
switch# config t
switch(config)#
Starts the global configuration mode
Step 2
[no] hardware module boot-order reverse
Example:
switch(config)# hardware module boot-order
reverse
switch(config)#
Switches the boot-up order for the modules
from a default low-to-high slot numbered
order to high-to-low slot numbered order.
Tip To use the defalut low-to-high order,
use the no hardware module
boot-order reverse command.
