Step 2. Upon power up, manually interrupt the boot process at the BOF prompt and
Step 3. Save the file and allow the boot loader to proceed with the boot process.
Step 4. After the CPM has booted up, on the active CPM, follow the prompts in the
During bootup, the IMM uses the configured MAC address to identify whether the
IMM is part of the stack and to determine its VC stack name and slot number before
loading the TiMOS images.
The IMM-only node communicates with the active CPM node in the boot loader
context. If the user has configured it to be part of the stack, the IMM-only node
obtains its slot number and the TiMOS images required to boot up from the active
CPM.
When the IMM-only node receives a VC discovery message containing the MAC
address and slot number, the IMM-only node obtains the location of the TiMOS
image (both.tim) and downloads it using the information received in the discovery
message. If an IMM-only node does not receive the VC discovery message with its
MAC address and slot number, it does not load the TiMOS image. Instead, the IMM-
only node will wait for a specific amount of time defined by the system, reboot, and
wait again to receive a VC discovery message with its MAC address. The IMM-only
node repeats this process indefinitely or until the operator removes the node from the
VC by disconnecting its stacking ports.
The following output is an example of a BOF configuration for an IMM-only node.

configure the following:
i. Specify standalone-vc for the boot loader parameter chassis-role.
ii. Specify imm-only for the boot loader parameter vc-stack-node-type.
iii. Note the MAC address of the IMM-only node. The MAC address used
for VC configuration is the chassis MAC address printed on the label of
the node.
You will need this information to configure the node in the TiMOS
context using the config>system>vc-stack-node slot-number mac-
address mac-address command on the active CPM, when the CPM is
up.
The slot number, image location, configuration location, IP addresses, and
route information do not need to be configured on the IMM-only node.
