5 Chaper 1: Overview This document is provided for AppEx customers (for system and network administrators with basic or advanced knowledge of networking). After reading this manual the administrators will be able to complete the following tasks independently: Installing and using LotWan Managing LotWan 1.1 Introduction LotWan is based on Zeta-TCP, a proprietary technology that speeds up all TCP-based network applications including data sharing, receiving and transmitting s, office automation, web applications, database systems, video streaming, disaster recovery, online gaming, web browsing,, etc. 1.2 Special Notes When LotWan is used in conjunction with VPN equipment: Under normal circumstances, LotWan should be deployed before the data enters into any VPN tunnel. When LotWan is deployed after the data enters into the SSL VPN tunnel (using TCP l to transmit data), TCP acceleration would still function correctly. For VPNs using IPSec, LotWan must be deployed before the data enters into the VPN tunnel, otherwise the acceleration will be neutralized. Chaper 2: Installation of LotWan To install LotWan, you will need the following: LotWan appliance Standard 1U or 2U racks L shape mounting brackets Screw sets AC power cords 2.1 System Indicators When the unit is turned on initially, the hard drive indicator is red. Once it has booted up, the indicator is turned off. The bypass light on the fiber NIC is not lit normally (no bypass mode); and it is lit when in bypass mode. The NIC indicator is orange normally, and blinks when data is being transmitted. 2.2 System Installation 1. LotWan can be mounted on a standard 19 inch rack. 2. Login into LotWan using the Web GUI via the default management interface as described in Chapter 3. Configure the physical network port as WAN/LAN interface according to customer configuration When configuring WAN/LAN interfaces, be sure to use the network interface with embedded bypass feature, and enable the bypass mode in the Administration System Setup tab 3. Login into LotWan using the Web GUI via the default management interface 4. Use screw set to lock the L-shape rack mount 5. Install LotWan onto the rack 6. Plug in supplied power cords and turn on the power switch The power connectors are at the back of LotWan. The input voltage range is 100V 240V 1 LotWan Appliance User Guide 2014 AppEx Networks Corporation. All rights reserved.
