Status Indicators
This section discusses the following topics:
AC Power Supply Status Indicators
Each AC power supply has an illuminated translucent handle that indicates whether power is present or whether a power fault has occurred.
| OK LED | Status |
| Green | A valid power source is connected to the power supply and the power supply is operational. |
| Flashing green | When updating the firmware of the power supply unit is being updated, the power supply handle flashes green. |
| Flashing green and turns off | When hot-adding a power supply, the power supply handle flashes green five times at 4 Hz rate and turns off. This indicates that there is a power supply mismatch with respect to efficiency, feature set, health status, and supported voltage. Replace the power supply with a power supply that matches the capacity of the other power supply. |
| Flashing amber | Indicates a problem with the power supply. |
Rack Installation
Each appliance provides an accessory kit that contains parts that are required to install the appliance.
The following sections list the installation parts provided by the accessory kit.

Upgrade the Host Image
Arista provides an ISO with all updated packages and a tool to mount the images ISO and upgrade the system.
Make sure you use the correct upgrade procedure based on your current CV Appliance configuration. The two basic upgrade procedures are:
Single-node configurations
Use the following procedure to upgrade a single-node CV Appliance configuration.
Note: Allow 20 minutes for the CVP application to be accessible again after the CV Appliance host comes up. The CV Appliance host will come up after the system reboots (running the upgrade script, which is done near the end of the procedure, automatically reboots the system).
Complete the following steps to upgrade single-node CV Appliance configurations.
Multi-node configurations
A rolling upgrade should be done when upgrading multi-node CV Appliance configurations.
The steps you use are exactly the same as the steps used for single-node configurations, except that you must repeat the procedure for each node.
The basic steps involved in performing the rolling upgrade are:
- Login to one of the CV Appliance hosts.
- Complete the upgrade using the steps in the procedure. (Make sure you follow the rules in the Important! notice below when performing the upgrade.)
- Wait until all CVX and CVP VMs are up and running before you begin the upgrade on the next host.
Note: Important! To complete the rolling upgrade, you must:
- Upgrade only one CV Appliance host (machine) at a time.
- Wait after each host machine is upgraded, until all CVX VMs and CVP VMs are fully up and running before you begin the upgrade on the next host in the cluster.
CVP takes approximately 20 minutes to be fully accessible after the system reboot (running the upgrade script, which is done near the end of the procedure, automatically reboots the system). Verify that CVP is accessible before you begin to upgrade the next CV Appliance host in your multi-node cluster configuration.
Complete the following steps to upgrade multi-node CV Appliance configurations.
CloudVision Physical Appliance Setup
You may need the following items to perform the procedures in this section:
- Key to the system key-lock.
- #1 and #2 Phillips screwdriver.
- Wrist grounding strap connected to ground.
- Rack mount kit instructions located in the shipping box.
Front Bezel
Removing the front bezel:
- Unhook the right end of the bezel and pull the bezel away from the system.

Locate the MAC Addresses for the CloudVision Appliance
The information tag is a slide-out label which contains system information such as Service Tag, NIC, MAC address for your reference. Record the MAC addresses in the CloudVision Worksheet.
Back Panel Ethernet Connections
On the back panel of the DCA-CV-100 CloudVision appliance, locate the Ethernet Integrated 10/100/1000 Mbps NIC connectors.
Note: The iDRAC interface shares the NIC1 physical interface but has a different MAC address.
iDRAC is an Intelligent Platform Management Interface (IPMI) that provides a GUI-based out-of-band interface for monitoring the hardware appliance. iDRAC uses NIC1 (see Figure 2-4) for its network connectivity using a unique MAC address.
Record the IP address and Hostname information in CloudVision Worksheet (see Appendix H).
Note: Subnet 1 is mandatory, but Subnet 2 and the use of Ethernet NIC3 and NIC4 are optional.
Note: iDRAC may also be refereed to as Lifecycle Controller.
DNS Entries
In order to manage your CloudVision cluster, it is often easier to connect to them by hostname as opposed to IP address. Fully qualified domain names (FQDNs) should be allocated to:
- Each of the CloudVision Appliance host machines.
- Each of the CloudVision Appliance iDRAC interfaces.
- Each of the CloudVision Portal (CVP) nodes.
- Each of the CloudVision Server (CVX) nodes.
Contact your DNS zone administrator for assistance.
CloudVision Appliance IP Configuration
The CloudVision Appliance Host and iDRAC IP addresses can be allocated in either of two ways:
Option 1: Using an available DHCP server
Option 2: Manual configuration (Requires terminal connected to VGA port)
DHCP Based IP Address Setup
Note: The iDRAC interface shares the NIC1 physical interface but has a different MAC address. You will need to take note of this MAC address to map the DHCP address for the iDRAC interface.
iDRAC IP Address
Using the iDRAC MAC from Locate the MAC Addresses for the CloudVision Appliance (see Figure 2), input an entry into the DHCP Server for the corresponding iDRAC IP address mapping to that MAC.
Host IP Address
Using the HOST NIC1 MAC from Locate the MAC Addresses for the CloudVision Appliance (see Figure 2), input an entry into the DHCP Server for the corresponding HOST IP address mapping to that MAC.
Turn the system on by pressing the power button located on the front of the system.
Manual IP Address Setup
Note: Direct IP Address Setup requires a terminal connected to the VGA port of the appliance. This section can be skipped if the Host and iDRAC IP addresses have been configured with a DHCP server. See Back Panel Features and Indicators for complete back panel descriptions.
iDRAC IP Address
The iDRAC IP address can be manually configured via the host's bash shell using the racadm tool. The racadm commands below are sequence dependent and must be entered in the following order.
Host IP Address
The host IP address can be manually configured via the host's bash shell. In order for the settings to be persistent, the following configuration must be completed.
