Need help installing rails on Cisco server

We bought this server and I cannot get the rails to install
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/hw/C240/install/C240/install.html#pgfId-1412140

The front guides go into the rack, but I cant get the back pegs in!

Anyone know how this works?

Zacharia, https://www.youtube.com/watch?v=CCXxrOOqCjs shows them snapping the rails in place in a square hole.  Mine are round.  So I removed the front pegs and the front mounts, but the back pegs WILL NOT seat.

Install the slide rails into the rack (see Figure 2-2):

 a. Align the slide-rail assembly inside the rack posts with the length-adjustment bracket (Figure 2-2, item 4) toward the rear of the rack.

 b. Compress the length-adjustment bracket until the mounting pegs (item 5) and locking clips (item 6) engage the desired rack holes on the front and rear rack posts.

– The mounting pegs fit square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC threaded holes. They fit the shape of the hole when the pegs are compressed.

– The smaller #10-32 round mounting pegs are enclosed in the center of the compressible  rear pegs. However, to use the #10-32 pegs, you must use a bladed screwdriver to remove the square/round  front pegs.

Have you removed all eight of the square/round pegs?

No only the four front ones.  Am I supposed to remove the round in the rear too?  If I do, what do I use to mount the rear?

I believe you need to remove the rear ones as well and there are small pegs underneath them for the small-hole racks.

Cisco worded this bit badly -
to use the #10-32 pegs, you must use a bladed screwdriver to remove the square/round  front pegs

They mean the square/round pegs sit in front of the #10-32 pegs so refer to them as front pegs, but these pegs are on both the front and back of the rails. They should have missed the word "front" out of the instruction.

The directions are TERRIBLE.  There are studs on the front but not on the back

Another model says "The mounting pegs that protrude through the rack-post holes are designed to fit round or square holes, or smaller #10-32 round holes when the mounting peg is compressed. If your rack has #10-32 rack-post holes, align the mounting pegs with the holes and then compress the spring-loaded pegs to expose the #10-32 inner peg."

You may end up messing about with adapter brackets such as shown at http://billyc5022.blogspot.co.uk/2011/09/cisco-ucs-c-servers-rack-mounting.html

These round to square hole adapter/extender kits are needed sometimes - https://www.racksolutions.co.uk/2u-adapter-kit-for-4-post-racks.html

This really irritates me.  How could Cisco send out a $30,000 server with cheap rails??????
I used some bolts I found lying around from another install and basically jimmy-rigged it together.  It's nice and tight, but it's not using all the parts that came with it.

What is your Rack Brand? IBM, Dell or something else?
