Description
Component
The JA2500 appliance has two hot-swappable cooling fans
that provide the required airflow to cool the appliance.
Cooling fans
The appliance power switch is used to power on or power off
the appliance.
Power switch
An empty power supply module slot is provided so that a
second power supply module can be added, for redundancy,
if needed.
Redundant power supply module slot
A single AC power supply module is shipped with the appliance
and provides power to the appliance. However, the appliance
can also be run on DC by using the DC power supply module
for the JA2500 appliance.
Power supply module
One LED is present on the power supply module:
•
Green indicates that the power supply module is powering
the appliance.
•
Amber indicates that the power supply module is on but it
is not powering the appliance (standby mode).

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
3
for 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
by the IP address type of a managed device. For a connection initiated by a managed
device, Junos Space listens on both IPv4 and IPv6 addresses of the device management
interface (eth3). Therefore, a managed device can communicate with Junos Space by
using its IPv4 or IPv6 address.
