Firmware recovery via HTTP
84/95
14.2 Prerequisites
·
The gateway is supplied with voltage and the backup firmware inside
the device is running (this is indicated by steady green light at the
POW
LED)
·
The gateway is disconnected from the Sercos network
·
The gateway is connected to an active DHCP server via local Ethernet
network
·
The gateway is connected via local Ethernet network to a configuration
PC with installed standard web browser
·
You have access to the firmware file which you want to download to the
gateway (the firmware is stored on the
SmartWire-DT Gateway
Solutions
product DVD in the
Firmware\EU5C-SWD-SERCOS
\Vx.x.x.x
folder).
·
You know the IP address, which the DHCP server has assigned to the
gateway. If not, install the Hilscher
Ethernet Device Configuration
Tool
on your configuration PC. This tool allows you to check the current
IP address of the gateway (if the configuration PC and the gateway are
connected to the same local Ethernet network). An installer for this
program can be found on the product DVD in the
Software
\EnDeviceCfg
folder (the program can also be installed by using the
menu of the product DVD.)
14.3 Step-by-step instructions
1. Use DHCP server to assign IP address to gateway.
Ø
Disconnect the gateway from the voltage supply.
Ø
Plug a cable connected to the local Ethernet network (in which a DHCP
server is active) into one of the Ethernet RJ45 sockets on the front side
of the gateway.
Ø
Reconnect the gateway to the voltage supply.
Note:
The
L/A
LINK/Activity LEDs of the Ethernet RJ45 sockets remain
dark when an Ethernet cable is plugged-in while the backup
firmware is running – even if a successful IP communication with an
local Ethernet network has been established.
Ê
The backup firmware running in the device now sends a so-called
DHCPDISCOVER message broadcast
into the Ethernet network,
requesting an IP address from a DHCP server. If a DHCP service is
available in the network, the gateway should be receiving a valid IP
address from the server within a few seconds.
