Never insert objects of any kind into the ventilation openings.
To avoid electrical shock, never attempt to remove the covers of the Google Search Appliance.
Always shut down the Google Search Appliance from the Admin Console before powering down the
hardware.
If you are working with the modem or local area network:
Do not connect or use a modem or telephone during a lightning storm. There may be a risk of electrical
shock from lightning.
To reduce the risk of fire, only use No. 26 AQG or larger telecommunications line cord.
Do not plug a modem or telephone cable into the network interface controller receptacle (NIC).
The device should be plugged into an uninterruptible power supply to make sure that the power source
is clean and that the Google Search Appliance is powered in case of a power outage.
WARNING: Never disconnect the power cord while the search appliance is running. Shut the search
appliance down from the System Shutdown page (in the Admin Console’s Main page) before
disconnecting the power cord. Last, to remove all power from the unit, disconnect the power cord.
Search Appliance Security and Resilience
Anti-Hacking Measures
All services within the Google Search Appliance sit behind a firewall. The firewall is the main source of
security for the device against malicious hackers. No communication can connect to or connect from
these servers without first going through the firewall. The firewall allows only a small set of ports to
pass into the system. For a complete list of the port numbers and their functions, see “What Ports Does
the Search Appliance Use?” in Planning for Search Appliance Installation.
Lockdown Security
The key to the bezel is supplied with search appliances GB-7007 and GB-9009, which you may unlock
only while installing the appliance in a racking system or replacing a hard drive. Do not attempt to open
the case of any other search appliance model.
