APPLICATION NOTE
Accelerator Card Installation
Introduction
This document describes how to install the accelerator card in the Aurorean
Network Gateway 7000 series (illustrated in Figure 1). The accelerator card
provides hardware-based IPSec encryption computation and processing, and
increases the throughput of the ANG-7000 series to 100 Mbps with 3DES
encryption. The hardware accelerator card works with Aurorean Release 3.1 or later.
NOTE
If you wish to install the accelerator card on a release 3.0 or earlier Network
Gateway, you must install Release 3.1 software before installing the card.
Refer to the Installation & Service Guide for detailed instructions on upgrading
the system software. If you do not have Release 3.1, contact Enterasys’ Global
Technical Assistance Center at 800 872-8400.

Before You Begin
Before you begin installation, you will have to gain access to the inside of the
ANG. If the ANG is mounted in a relay-style rack, you can install the card while
the ANG is in the rack if there is enough room on top of the ANG (at least 12
inches of clearance) to open the ANG’s cover. If there is not enough room you will
have to remove the ANG from the rack.
If the ANG is mounted into the rack with sliding rails, you can easily remove the
ANG from the rack.

3. Insert the card fingers into the PCI connector, making sure the card flange is
seated in the respective slots on the back of the ANG.
4. Replace the card flange holding plate with the two mounting screws.
This holding plate will capture the card flange and hold it securely against the
back of the ANG. Refer to Figure 12.
Figure 12 Accelerator Card Installed
Replacing the Cover
In order to replace the cover, reverse the three steps in the section “Removing the
Cover” on page 3.
1. Set the cover as shown in Figure 6. Place the front of the cover about 1/2 inch
behind the front edge of the chassis.
2. Make sure the sides of the cover are inside the sides of the cabinet. The slots
on the cover will sit over the mounting screw inserts on the side of the chassis
and allow the cover to seat itself on top of the chassis sides.
If the cover will not seat onto the chassis sides, the slots are not aligned with
the screw inserts. Move the cover (back or forward) accordingly to allow the
cover to seat itself onto the chassis sides.
3. Push the cover forward until the screw holes align themselves as shown in
Figure 4.

Re-installing the ANG-7000 Series in the Rack
Refer to the section “Removing the ANG-7000 Series from the Rack” on page 2, and
reverse the steps to re-install the server into the rack. Connect the power cord to the
server. Connect the Ethernet cables to the back of the unit.
Checking the Accelerator Card
If you have System Software Release 3.1 loaded on the ANG-7000 and subsequently
install the accelerator card, the ANG-7000 series will automatically detect the presence
of the card and activate it. No further software configuration is required. You can
verify that the accelerator is installed and working though by issuing the dmesg
command on the Command Line Interface (CLI). To do so, perform the following
steps:
1. On your desktop, click Start, select Programs and double-click Command
Prompt.
2. Telnet to your ANG. Type: telnet
xxx.xxx.xxx.xxx (your ANG IP address) and
press ENTER.
3. Login and press ENTER.
4. Type your password and press ENTER.
5. Issue the dmesg command by typing dmesg and press ENTER.
In the resulting output, look for the following text toward the end of the file to
verify the installation was successful and the card is working correctly:
Aurorean Network Gateway interface for Bluesteel Networks
ubs5501
ubs5501 library version 1.0
Bus 0, device 22533, IRQ 7, Address FFAE0000
Subsec: Device crytpo selftest passed! 0
If the accelerator is not installed, you will get the following text:
ubs5501 library version 1.0
Subsec: Device startup failed
The ANG-7000 series will operate properly without the accelerator card.
