Sierra Information

Before installing Sierra, ensure that you are logged into your Windows account with administrative privileges. You will also want to be sure to download and install the latest version of Java. Note that in some cases it may be necessary for your local IT to intervene, especially in cases of firewalls, unprivileged accounts, and the presence of programs such as Deep Freeze.


Installing Sierra

To install Sierra, follow these steps:

  • Run the installer
  • If User Account Control warns you, choose Yes
  • Follow the prompts in the installer
  • Step #2 asks for an Install Folder
    • C:\Sierra Desktop App\ is common
  • Step #4 asks for a server
    • Use cat.opal-libraries.org
    • Do not use an IP address
  • The installation will complete
  • Note that the first time you run Sierra, it will spend several minutes downloading updates

Troubleshooting Sierra

Issues with installing or running Sierra can be difficult to diagnose and in many cases your local IT will need to be involved. Below are the most common issues.

Issue Solution
Firewalls

Local or campus firewalls can block information flowing to Sierra. You will want to ensure that the firewall allows access to the Sierra server, which has the IP address of 66.11.2.33. You will also want to ensure the following ports are not blocked:

22 80 91 210 443 499 1031
2082 4440 4441 4442 4443 4444 4445
4446 4447 4448 4449 64000 64001  
Firewalls - RFC Compliance

The setting "Enforce strict TCP compliance with RFC 793 and RFC 1122" can cause dropped packets for Sierra. Make sure this setting is disabled. Other settings to disable would be "TCP checksum enforcement" and "TCP handshake timeout". For Sonicwall devices these settings are located under Firewall Settings > Flood Protection.

Software Conflicts

Other software may interfere or prevent Sierra from installing or running. Start by temporarily disabling firewalls and antivirus software.

AVG Antivirus
Deep Freeze
Windows Firewall

Sierra Won't Load

Sierra polls the printers visible to your PC at the time of launch. Multiple printers will take longer to check than one or two. Occasionally, a disconnected printer or network printer can cause the Sierra Desktop Client to take several minutes to load, so be sure to remove or disable any printers if appropriate.

IP vs Hostname

The Sierra installer initially asks for a server address. You will want to use cat.opal-libraries.org instead of an IP address. To check or change this entry:

  • Navigate to C:\Sierra Desktop App\
  • Double-click on the file iiirunner.lax
  • If asked, choose to open the file with Wordpad
  • About 25 lines down from the top, confirm or change the line:
    lax.command.line.args=ip=cat.opal-libraries.org port=64000
