1OVERVIEW 3
1OVERVIEW
This Netropy 40G Hardware Guide describes the physical hardware of the Netropy 40G Network
Emulator. The companion User’s Guide describes the installation, configuration, and operation of
the Netropy network emulation functionality. A separate Quick Start Guide provides a walk-
through for first time configuration.
The Netropy 40G contains no user serviceable parts. Opening the chassis voids the
warranty. If you believe your unit is not functioning properly, see Section 8 for
information on obtaining support.
This guide is for the Netropy 40G hardware revision –S1.

2INCLUDED ITEMS
The Netropy 40G shipping carton contains the following items:
Netropy 40G hardware unit
Slide rail kit and rack ear brackets
Netropy 40G Quick Start Guide
AC power cord (U.S.) quantity 2
RS-232 DB9 serial cable

3FRONT AND REAR PANELS 5
3FRONT AND REAR PANELS
3.1 Front Panel
The front panel of the Netropy 40G contains:
Power LED: Lit green when the unit is powered on.
Power Button: Press the power button on the front panel to turn the device on or off.

3FRONT AND REAR PANELS 6
3.2 Rear Panel
The rear panel of the Netropy 40G contains (from left to right):
Redundant Power Input: Dual IEC C14 sockets for redundant power input. U.S. and Canadian
customers should use the supplied power cords to connect both sockets to a power outlet.
International customers may need to substitute a local power cord with a standard IEC C13 plug.
The Netropy 40G handles AC power input from 100 to 240 V. If power is supplied to only one of
the power inputs or if one of the power supplies fails, the system will sound an alarm.
CONSOLE: Console interface using RS-232 with a DB9 connector. See Section 7 for a pin-out of
the console interface.
MGMT: Gigabit Ethernet interface with a standard RJ45 connector for management of the unit
over the network.
PORTS 1 –2: Two 40 GbE QSFP interfaces. See Section 6 for details. The top LED on each port
glows green when link is established. The amber LED below blinks to indicate activity.
Please ensure the space around the fan outlets on the back panel and the air intakes
on the side panels remains unblocked to provide adequate airflow and prevent
overheating.

4CAPACITY LIMITATIONS 7
4CAPACITY LIMITATIONS
The Netropy 40G can forward up to 40 Gbps of packets in each direction for an aggregate
capacity of 80 Gbps.
Each port can forward packets at a rate of 16 million packets per second (with 64 byte packets)
and an aggregate limit of 32 million pps (with 64 byte packets).
These limits apply regardless of whether emulation is on or off. These limits may be reduced
depending on the classification methods used.
The maximum one-way latency that the Netropy 40G supports depends on data throughput and
packet size. The chart below summarizes a few typical examples for traffic in one direction. To
calculate the maximum latency in each direction for traffic in both directions at the listed rate,
divide these maximum one-way latencies values in half. The listed values are based on actual
data throughput, not path bandwidth settings. Users who need to emulate latencies close to
these limits are advised to contact Apposite to discuss their specific requirements. Maximum
latencies of over 20 seconds are not specifically listed, but are not limited to 20 seconds and may
be much larger than 20 seconds.
The maximum emulation bandwidth may be limited below the hardware capacity by the device’s
license key. See the Netropy User’s Guide for more details on the license key.
