Hardware shutdown procedure
The VCS uses a hard drive for storing logs. We recommend that you shut down the appliance prior to it being
unplugged to ensure a clean shutdown process. This can be done from the web interface.

Network support
The VCS is an H.323 and SIP compliant device and is designed to be connected to an 802.3 IP network.
The first (or with dual network interface option, the first two) 802.3 Ethernet ports are used which are labeled
LAN 1 (and LAN 2); the remaining two are currently unused. The Ethernet interfaces on the VCS support both
manual configuration and auto speed and duplex detection for 1000Mbit Full Duplex, 100Mbit Full or Half
Duplex or 10Mbit Full or Half Duplex.

We recommend that speed and duplex settings are set to auto unless the Ethernet switch that the VCS is
connected to does not support auto-negotiation; if manually configured, ensure that full duplex is selected.
