Activating ceilometer using PuTTY

Laptop with terminal software that supports SSH (for example, freeware TeraTerm or latest version of PuTTY)
Ethernet maintenance cable

Open the terminal software.
In the PuTTY Configuration window, type in Host Name the following:
```
admin@172.17.0.2
```
Do not modify the other settings.

Select Open.
In the Security Alert window, accept the key.

The ceilometer asks for a username and a password or only for a password.

If it asks for a username, type admin.

When it asks for a password, press ENTER to skip the password. The password is defined later on.

If the device does not allow you to skip the password step, it is possible the device is already activated. Type the password set during previous activation. If this password is unavailable, factory reset the device to start the activation process again.

When prompted, type the device activation code.

The device activation code is case insensitive. The device activation code may contain hyphens or spaces, but you can type it without them, as one string.
When prompted, define a password for the admin user and press ENTER.

The password is case sensitive.

For security reasons the password does not display in the interface window as you type it, but the keystrokes register. Type the password as normal.

CAUTION If you forget the admin password, you cannot retrieve it without factory resetting the device (requires device activation code).

Follow generic principles in creating a good strong password.

When prompted, repeat the password.
With the CLI, change the access level to 1:
```
level 1
```

Configure CL61 data port (eth1) IP settings for your operating environment according to your known system information.

The maintenance port settings are fixed and cannot be changed.

If you are using a dynamic IP setup, enable dynamic host configuration protocol (DHCP).
```
set eth1.address.dhcp ON
```

If you are using a fixed IP setup, disable dynamic host configuration protocol (DHCP), and type the network settings manually.

By default, CL61 uses the following settings:

Table 1. Default connection settings for data line (ETH1)
Property	Value
DHCP	OFF
IP address	192.168.2.102
Network mask	255.255.255.0
Default gateway	192.168.2.1
DNS1	192.168.2.1
DNS2	OFF

If you need to change the settings, use the following commands.

set eth1.address.dhcp OFF
set eth1.address.ip1 <IP address>
set eth1.address.nm1 <netmask>
set eth1.address.gw1 <gateway>
set eth1.address.dns1 <dns1>
set eth1.address.dns2 <dns2>

Depending on your setup, you can set the gateway and one or both of the domain name system (DNS) parameters OFF.

Restart the device after changing DNS settings.

Set the network time protocol (NTP) source or sources as follows.

set time.sync.ntp1 <ntp1>
set time.sync.ntp2 <ntp2>

Alternatively, set the NTP parameters OFF and give the UTC time manually.

set time.sync.ntp1 OFF
set time.sync.ntp2 OFF
set time.unit.now <YYYY-MM-DD HH:MM:SS>

By default, CL61 uses the following NTP settings:


Property	Value
NTP1	2.openembedded.pool.ntp.org
NTP2	OFF

Vaisala recommends using NTP time. When using manual setup, the time is reset when the device resets or power is disconnected from the device, after which you need to set parameter time.unit.now again.

Check the settings.
```
get eth1
get time
```
If you use dynamic IP setup, check the required IP address from the DHCP server, or serial CLI with the get eth1 command.
Reset the system.
```
reset
```
CL61 reboots with the new settings and the terminal software disconnects.
Close the terminal software.
Disconnect the maintenance cable and connect the CL61 Ethernet cable to your operating environment. If you continue with configuring data transfer settings, keep the maintenance cable connected.

Place the device activation code stickers in a suitable location safe from unauthorized access. The device activation code is needed later on if you have to reset the device.

To continue configuring the ceilometer or to change the defaults if necessary, see Vaisala Lidar Ceilometer CL61 Configuration and Maintenance Guide.
