Powering On and Initially Configuring the CTP150 Device


Powering On the CTP150 Device

In this procedure we assume that the device is already connected to a power source.

For specifications on the electrical requirements for the device, see CTP150 Platform Specifications.


Evaluate the overall loading of the branch circuit before you install any equipment into a rack.

To power on the device:

  1. Verify that the power source is operational.
  2. Inspect all grounding and power connections to the device chassis.
  3. Confirm that all cable connections are secure.
  4. Switch any available power switches to ON.
  5. Monitor LEDs to verify that the device is booting properly.

    The device goes through a boot process. When a prompt appears on the console, the device is ready to be configured. If the device is new, it boots to a first boot script. If the device is already operational, it boots to a login prompt.

During initial power-on, the components of the platform run boot code, go through a series of self-diagnostic tests, and synchronize with each other.

When the tests are complete, use the LEDs on each module to determine the status of the device. Observe the module LEDs on the front or rear components.

Configuring the First Boot Script for the CTP150 Device

For the first-time boot process, there is a series of login prompts that require the following settings:

  1. Default username (ctp) and password (ctp). (We recommend that you change the root password after entering the default.)
  2. Supported protocol or protocols—(0) IPv4 only, (1) IPv6 only, or (2) IPv4 and IPv6. Enter the appropriate number value.
  3. Default interface—From the list of available devices, such as eth0 and eth1 (or more), enter the one to be the default.
  4. Hostname of the device.
  5. IP address of the interface—Enter the IP address of the selected interface, or accept the loopback address ( by default.
  6. Netmask of the IP address—Enter the netmask (such as, or accept as the default.
  7. Gateway IP address—Enter the IP address of the gateway, or accept the local address ( as the default
  8. Maximum transmission unit (MTU)—Enter the MTU in bytes, or accept 1500 bytes as the default.
  9. Static routes added to the default interface, if any.
  10. Date and time GMT (more precisely, UTC)—Enter these separately in digits for the month, day, hour, and minutes in Coordinated Universal Time (UTC), or accept the internal settings.

    The device goes into startup mode.
