TFTP uploading (Power-On Reset Entry Mode)

If a valid main ﬁrmware is not loaded or a power failure occurred during TFTP uploading Application

Entry Mode, then the TFTP uploading Power-On Reset Entry Mode must be used. In this mode, the

Midspan device must use a default IP address 10.0.2.5 with a Subnet mask of 255.255.255.0 for a

TFTP upload. The procedure is as follows:

1. Conﬁgure the PC as a Static Mode by setting Start » Settings » Network Connections » Local

Area Connection » Properties » Internet Protocol (TCP/IP). In the Internet Protocol (TCP/IP)

Properties window, set a static IP as shown in Fig. 32.

Figure 33: Set static IP in Internet Protocol (TCP/IP) Properties window

2. Connect the midspan directly to the PC with a Cat5e cable (An older PC may need a crossover

Cat5 cable.)

3. In the Command Prompt Console, type the following command but do not execute it:

tftp 10.0.2.5 put “C: \......\POEA-x.x.bin” , make all the appropriate ﬁle path changes.

4. Power up the midspan. If the device is already powered, turn it off by unplugging it for several

seconds, and then reconnect it to a power source.

5. Once the green LED on management RJ45 port blinks 3 times, quickly press Enter to run the TFTP

command. It must be executed at the right moment as soon as the power turns on.

6. After a successful TFTP boot loading process, restore your PC’s Internet Protocol (TCP/IP) settings

to <Obtain an IP address automatically> and < Obtain DNS server address automatically > to

allow normal network activity.
