Junos Space Appliance Overview
The Juniper Networks Junos Space Appliance is a dedicated hardware device that is
engineered to provide the computing power and meet specific requirements to be able
to install and run the Junos Space Network Management Platform. Junos Space Network
Management Platform is an open, extensible platform that simplifies the management
and orchestration of networks, and allows you to develop and host applications that
simplify network operations, scale services, and automate support. The all-in-one design
of the Junos Space Appliance enables administrators to easily deploy Junos Space
Network Management Platform.
Junos Space Appliances are currently available in one model: JA2500.
The JA2500 appliance has a 2-U, rack-mountable chassis with dimensions of 17.81 in. x
17.31 in. x 3.5 in. (45.2 cm x 44 cm x 8.89 cm). The JA2500 appliance ships with a single
AC power supply module; an additional power supply module can be installed in the
power supply slot in the rear panel of the appliance. In addition, the JA2500 appliance
can also be powered on by using one or two DC power supply modules.
The appliance has six 1-TB hard drives in a RAID 10 configuration. Two externally accessible
cooling fans provide the required airflow and cooling for the appliance.

Field-Replaceable Units on the JA2500 Junos Space Appliance
Field-replaceable units (FRUs) are components that you can replace at your site. The
FRUs in the JA2500 Junos Space Appliance are of the following types:
•Hot-swappable FRUs: You can remove and replace these components without powering
off the appliance.
•Cold-swappable FRUs: You must power off the appliance in order to remove, replace,
or add these components.
The FRUs supported in the JA2500 appliance are listed in Table 3 on page 4.

Junos Space Ethernet Interfaces Overview
This topic applies to the following Junos Space Appliances: JA1500 and JA2500.
A Junos Space Appliance has four Ethernet interfaces; three interfaces can be used and
one is reserved for future use. The Ethernet interfaces are labeled ETH0,ETH1,ETH2, and
ETH3 for the JA1500 Junos Space Appliance, and 0,1,2, and 3for the JA2500 Junos Space
Appliance.
The Ethernet interfaces eth0 and eth3 support both IPv4 and IPv6 addresses. As a
separate IP address is available for each IP stack, for any connection initiated by Junos
Space, the source IP address (that is, the IPv4 or IPv6 address) of the connection is bound
