What is it and what is it for?

 

This is an ADSL modem from a good manufacturer (Cisco) with inbuilt router and 4-port 10/100 switch.

 

A representative "sh version" output is shown below. It is running IOS version 12.3(2)XC2.

 

See here for more detailed information

 

What is included?

 

Each purchase is a modem, a power supply and a Cisco console cable.

 

My photos usually show the complete contents of what is included in the auction. If you think something else that's not shown should be included, don't assume it is. Contact me via this site and ask before bidding.

  

Sometimes I have more than one of the same item and I only take a photo of one. This means that, while the photo is of an item the same as that in this sale, it may not be the actual one I send you. It will not be any inferior to the photo, and should be virtually identical.

 

If you're bidding internationally, note that any power cord/adaptor etc will be a standard Australian type. I will not usually include the cord when sending overseas (this keeps your shipping cost down). If this is a problem, contact me before bidding.

 

Condition 

Cosmetic 

Cosmetically, this is in good condition. It's not new so there are a few scratches, scuffs and marks on it. There may be remnants of labels on it. Of course, none of this affects its operation.

 

Functional 

Functionally, I have tested it by connecting to the console port, observing the POST, and running it for a while, and it's working fine under those circumstances. There are no passwords set, so you can configure it to your requirements.

 

I'll give a 30-day DOA warranty. If it doesn't work 100% (except for any issues noted in this listing), I'll refund your money and pay for postage to return it. I can only offer this to buyers within Australia, but if an International buyer has a problem, I'm happy to negotiate.

  

Detailed information about the item

I had a link to a page on the Cisco website which give more information about this item in here, but eBay made me remove it (perhaps because they are paranoid about people putting in links to their own websites). This is annoying, because the link was there to help you get more information about the item, but I have to obey eBay's rules. Sorry about that.

The following is included in the document above:

"The Cisco 837 routers are asymmetric digital subscriber line (ADSL)-over-plain old telephone service (POTS) routing devices. They have an integrated 4-port Ethernet switch for the LAN and an ADSL physical interface for the WAN, allowing the routers to connect a corporate telecommuter or small office to corporate LANs and the Internet.

The routers support high-speed encryption, the10/100BASE-T switch, and dial backup functionality via the auxiliary console port. The autosensing function in these routers eliminates the need for a crossover cable and allows the router to detect medium dependent interface in normal mode (MDI) or medium dependent interface in crossover mode (MDIX) in any other PC or hub with a straight-through cable or a crossover cable. The routers are capable of bridging and multiprotocol routing between LAN and WAN ports.

The dial backup feature allows the user to connect an analog modem to the console port as a backup link to the WAN in case the ADSL service goes down. This feature gives the Cisco 837 routers a high level of performance and security.

The Cisco 837 router is designed with both hardware-based and software-based encryption. The Cisco 837 routers support the addition of Flash memory or DRAM, either as a factory upgrade or a field-installed option."

 "Features

 10/100BASE-T Ethernet switch        

                Provides connection to 10BASE-T (10-Mbps) or 100BASE-T (100-Mbps) Ethernet networks. Compatible with 10/100-Mbps devices.

ADSL port             

                Provides connection to ADSL network. Does not support auto-switch function.

Flash memory      

                8 MB of Flash memory; up to 16 MB of expandable Flash memory on the Flash module.

Synchronous dynamic RAM (SDRAM)             

                32 MB of SDRAM on board.

Ease of installation             

                Color-coded ports and cables reduce the chance of error.

Cisco IOS software             

                Supports Cisco IOS software.

LAN interface      

                Fully compliant with IEEE 802.3 and IEEE 802.3u. Automatic MDI/MDIX crossover function eliminates the need for crossover cables.

Cisco Router Web Setup    

                Provides a web-based software tool for basic configurations.

Console port        

                Provides connection to terminal or PC for troubleshooting and for software configuration using a command-line interface. This port is configured as a data communication equipment (DCE) port with the hardware handshake.

Dying gasp           

                Provides dying gasp function. If the router is about to lose power, this function detects the situation and sends a signal to warn the digital subscriber line access multiplexers (DSLAM) about the impending line drop.

Wall-mounting feature     

                Brackets on the router bottom provide for mounting the router on a wall or vertical surface.

IPSec Hardware Accelerator             

                The Hifn 7902 security processor implements symmetric key encryption, public key encryption, authentication, and data compression in hardware. Algorithms implemented by the processor include Data Encryption Standard (DES) and Triple DES (3DES); Secure Hash Algorithm (SHA-1), Message Digest 5 (MD5), Hash-based Message Authentication Code (HMAC); and Lempel-Ziv-Stac (LZS) compression and Microsoft Point-to-Point Compression (MPPC)."

Here's the output of a show version command. Note that they are all the same except for the bits in red. These bits are things like serial numbers, uptimes, last restart method, memory distributions (all are total 48MB). The only exceptions are the ROM bootstrap version (all are at least 12.2(8r)) and processor revision (0x500 or 0x501)

Shipping

Please use the calculator provided by eBay.

 

Pickup (from Cannon Hill) is free. Contact me to check before bidding or paying if you want more details.

 

Postage costs can be combined on multiple items. Note that the eBay calculator for multiple purchases isn't very flexible. If you are planning to buy more than one item, contact me if you want a good postage estimate.

 

If using PayPal, the item must be sent with proof of postage as per PayPal requirements. This is included in al the postage options in the calculator for each listing.

 

For PayPal payments, the item(s) must be sent to the address in the PayPal notification email that I receive. If you want it sent somewhere other than your “default” address, you’ll need to change this on the way through the payment process.

 

See my “About me” page for details of how my shipping costs are determined.

 

Payment

You can pay by

• any method offered through eBay
• cash on pick up locally (Brisbane)

Any payment method must be in Australian dollars, negotiable in Australia.

 

This is a private sale, so no GST is involved.

 

 

General conditions

International buyers are responsible for any customs duty, etc. I'll describe the item and price accurately on the customs declaration. You'll also need to confirm, before you bid, that the item is permitted to be imported.

 

Due to some bad experiences, I have had to block bidders from a couple of countries. If you find yourself in this situation, and you're serious, contact me and, if your rating is OK, I'll make the appropriate arrangement so you can bid.

 

I always leave feedback.

 

Any questions, please contact me via this site.

OK ….. here’s the deal ….

 

What do I expect from you?

 

If you buy the item, I expect you to contact me within 3 days and arrange to pay within 7 days. I need you to provide me with a correct address for me to send the item. When you get the item and you’re happy with it, I’d appreciate feedback on the eBay site.

 

What can you expect from me?

 

I value my eBay rating and I have every intention of providing good value for you. I recognize that you’ve only seen a photo and read my description of the stuff you’re buying. I’m sure there are odd cases where I have omitted to put in something that you may consider important but I’ve just forgotten or maybe didn’t realize was important. You’ll only find this out when you get the stuff.

 

If there is some unforeseen discrepancy between what you’ve expected and what you get, I’ll usually refund your money. If it’s obviously my fault, I’ll also refund your postage. If it’s worthwhile, I’ll also pay for you to send it back. Note that this only applies to “unforeseen discrepancies”, i.e. it doesn’t cover things that were in the item description, or could be seen in the photo.

 

I’ll leave feedback on the eBay site for you. If all goes as well as it nearly always does, it will be positive. If someone doesn’t pay I will use the eBay Unpaid Item process and, if it goes to completion without payment, you may receive an Unpaid item Strike which could affect your ability to buy stuff on eBay.

Shipping costs and details

 

The following applies unless I have specified shipping costs as being fixed (usually only within Australia). eBay will calculate the postage based on my measurements of weight and size of the parcel. This will be based on best estimates. Sometimes, when I get to the Post Office, they’ll charge me slightly more or less. If it’s more, I’ll wear it. If it’s less, I’ll offer you a refund if the difference makes this worthwhile (usually if it's above about $2).

 

I'll try to get the best pricing for postage (on your behalf) and that may sometimes mean that I need to slightly deface the packing (box, etc) of the item, for example by putting packing tape or an address label on it. If you want to keep the packing looking as pristine as possible (for example, if you plan to resell it, or give it as a gift), please tell me when you buy it and I'll pack it differently. Packing or postage costs may be slightly different in this case. Again, please ask first if this is likely to be a problem.
