High Availability Interfaces
There are no dedicated High Availability (HA) interfaces on the NetScreen-ISG 2000;
therefore, you must select and configure the HA ports once the system is running. The HA
ports allow you to cable two devices together, and configure them to work as a
redundant
group
. A redundant group consists of a master device and one backup device. If the master
device fails, the backup device takes over as the new master, thus avoiding interruption of
services. Any number and type of interfaces, from the four interface modules, can be used
as an HA port.
For information on cabling for High Availability, see
“Connecting the NetScreen-ISG 2000
for High Availability” on page 26
.
The Fan Module
The NetScreen-ISG 2000 has a three-fan module, which you can access on the left front
side of the chassis.
Note:
It is recommended that you use mini-GBIC interface modules when possible. Do not
mix mini-GBIC and 10/100 Mbps ports as HA ports. If you do not have a mini-GBIC
interface module, you should use at least two 10/100 Mbps interfaces. For more
information on HA configuration, see the
NetScreen Concepts & Examples ScreenOS
Reference Guide
.
Warning:
If a fan stops operating due to failure or removal, the system continues to run.
Be sure that the fan tray is not empty for more than two minutes; otherwise, heat failure or
permanent damage can occur.
