SECTION 1OVERVIEW 3
1OVERVIEW
This Netropy N91 Hardware Guide describes the physical hardware of the Netropy N91 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 N91 contains no user serviceable parts. Opening the chassis voids the
warranty. If you believe your unit is not functioning properly, see Section 9 for
information on obtaining support.
This guide is for the Netropy N91 hardware revision –T1.

SECTION 3FRONT AND REAR PANELS 5
3FRONT AND REAR PANELS
3.1 Front Panel
The front panel of the Netropy N91 contains, from left to right:
Power LED: Lit green when the unit is powered on.
MGMT: Gigabit Ethernet interface with a standard RJ45 connector for management of the unit
over the network.
CONSOLE: Console interface using RS-232 with an RJ45 connector. See Section 8 for a pin-out of
the console interface.
Reset: The small hole to the right of the console port is used to reset the system to the factory
default configuration. Reset capability is only active during system boot-up. To reset the system,
insert a paper clip or toothpick into the hole, reboot or power cycle the device, and continue
holding the reset switch for 20-30 seconds until the system reboots again.
PORTS 1 – 8: Eight Gigabit Ethernet ports consisting of eight 10/100/1000baseT Ethernet ports
with RJ45 connectors (standard), eight modular SFP ports (optional), or four each RJ45 and SFP
ports (optional), used for network emulation. Interfaces support jumbo frames up to 9 KB.
The RJ45 interfaces have two LEDs. The LED on the left indicates that link has been established
and flashes to indicate activity. If the link is up, the LED on the right glows amber to indicate
connectivity at 1 Gbps, green for 100 Mbps, and off for 10 Mbps.
The SFP interfaces have two LEDs. The LED on the left indicates that link has been established and
flashes to indicate activity. If the link is up, the LED on the right glows green to indicate
connectivity at 1 Gbps.

SECTION 3FRONT AND REAR PANELS 6
3.2 Rear Panel
The rear panel of the Netropy N91 contains:
Fan outlets: Hot air is vented through the fan outlets.
Power input: Standard IEC C14 socket for power input. U.S. and Canadian customers should use
the supplied power cord to connect the Netropy N91 to a power outlet. International customers
may need to substitute a local power cord with a standard IEC C13 plug. The Netropy N91
handles AC power input from 100 to 240 V.
Power switch: To turn on or off, rock the switch onto the power icon and hold for 5 seconds
until power light turns on or off.
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.

SECTION 4CAPACITY LIMITATIONS 7
4CAPACITY LIMITATIONS
The Netropy N91 can forward up to 1 Gbps of packets in each direction across all 8 emulation
interfaces at full line rate. This capacity can be reduced depending on the classification method
used.
The maximum one-way latency that the Netropy N91 supports depends on data throughput and
packet size. The chart below summarizes a few typical examples for traffic in one direction on one
engine. To calculate the maximum latency in each direction for traffic in both directions at the
listed rate, or to calculate the maximum latency when using multiple engines at the same rate,
divide these maximum one-way latencies by the number of ports through which traffic is
entering. 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.
