I looked at a client’s site… The routerboard is labled Routerboard 411/411R , but it looks like a 411A with a Minipc slot and not onboard wireless. the current wireless in the slot is a AWPCI085H that seems to hae stopped working… according to the client, this will be the second wireless that stopped working the last 7 months.
The grounding is correct and it was suggested a R52 card needs to be installed. The arial is a D/G 1004804 omnidirectional.
Question .. Any reason why the wireless boards would stop working ??
Second .. where can i find info on the LED501 - LED505 to see what they indicate ?? and what does the beeps mean ?? I can not fine thisin the user manuals…
the PCB is labelled such way, but it doesn’t include a radio. You can identify the model in RouterOS “/system routerboard” menu. Or in Winbox title bar. The correct model name should also be on the sticker that has the serial number.
LEDs are
Six LEDs (LD 501-506) are located to the right of the Serial port. Their functions are as follows:
• LED 1-5 are all user programmable
• LED 4 when not programmed shows Bootloader activity
• LED 5 when not programmed shows NAND activity
• LED 6 is used for Wireless activity (not active in current RouterOS versions)
cards could burn down for several reasons:
manual-tx-power is used and set above the card’s capacity (overclocking will damage it)
ESD damage during storms. use shielded cables and lightning arrestors in addition to grounding. also read if your grounding is correct;
