Colo@ FAQ

What type of cabinets are used at Colo@?

A: We utilize Dell 4210 and 4220 cabinets with square mounting holes.

What type of power outlets connect to your cabinets?

  • 120V - L5-20
  • 120V - L5-30
  • 208V - L6-20
  • 208V - L6-30
What would you recommend for IP KVM?

A:Colo@ recommends either using servers with IPMI capabilities or the use of an IP KVM such as a Dell 2161DS.

Why would I want IP KVM?

A:IP KVM allows you to access your server exactly as if you were sitting in front of it with a keyboard and monitor. It allows you to access BIOS level menus and commands. IP KVM saves a lot of expense by allowing you to do anything and everything outside of physically handling the hardware.

Based on my colocation space, which PDU should I use?

A:f you have a full cabinet, we suggest the following:

  • APC AP7930 - 20A 120V
  • APC AP7932 - 30A 120V

If you utilize a 1/2 cabinet, we suggest:

  • APC AP7901 - 20A 120V

If you colocate at 1/4 cabinet, we provide a single APC AP7901 - 20A 120V, on a 10A circuit.

What is Colo@'s power usage policy?

A:We use an 80% usage policy. This keeps our power system and your equipment safe from spikes or over-usage. If you utilize more than 80% of your allotted power, we will request that you power down some equipment or that you upgrade your power allotment.

What network equipment would you recommend?

A:We recommend the following:

  • Firewalls: PIX 525, ASA5505, or ASA5510.
  • Basic IP Routing:(Layer3) : Cisco 3550/3560/3750 (10/100) 3750G (10/100/1000)
  • Basic Switch: (Managed Layer2): Cisco 2950/2960 (10/100 w/1000 Uplink) Cisco 2960G (10/100/1000)
  • High-End Router: Cisco 6500.
How do I request IPs?

A:Please login to and let us know what you need. Once there, please select "IP Allocation Request." This will let you justify/request more IP space.

How does 95th percentile bandwidth billing work?

A:You may have seen the term "95th percentile" used when discussing bandwidth billing. It's a common way to bill bandwidth usage, but unless you're familiar with the concept, it may seem rather strange. If you've always wondered how it works and why it's used, read on...

95th percentile billing is the predominantly used method to bill bandwidth. Rather than bill based on the total traffic used, we bill based on a quoted per-megabit rate. This allows us to evaluate the sustained usage of your connection. Basically, at the end of each billing cycle you are only billed for 95% of your total bandwidth usage with the final 5% getting discarded.

Simply put, this means that you pay as you use the bandwidth with large bursts of traffic not figuring into your monthly bill.

We measure traffic in 5 minute intervals so what that means is that over the course of 500 minutes, we don't bill you for the 25 minutes of highest bandwidth usage.

I need software licenses. Do you have any available?

A:Yes! Colo@ can provide you with many software licenses. We have the following available:

  • R1Soft
  • Softaculous
  • cPanel
  • Fantastico
  • Ksplice
  • Microsoft Server 2008
  • Microsoft MS-SQL
  • Microsoft Sharepoint
  • Many more...
Do I need to ship mounting rails with my server?

A:Yes! Every server mounted in our cabinets requires proper rails to be installed and used.

What length network cables should I use?

A: We recommend using color coded network cables between 5' - 7' in length.

Do you have OS install disks for me?

A:No. You should plan on bringing two sets of installation media of your chosen OS. Why two sets? Just in case there is a problem with one. It's always easier to have a backup than it is to go and find another copy.

What tools or other equipment would you recommend I bring along?

A:The following items will be handy to have around:

  • Assorted screwdrivers.
  • Wire cutters.
  • Needle-nose pliers.
  • Flashlight.
  • Velcro cable management strips.
  • Battery powered labeler.
If I need hardware, who should I contact?

A:We have an on-site hardware broker. He will provide you with a good deal and we use his services frequently and gladly refer customers to him. His contact information is:

What are some "best practices" you would recommend?

A:The following are some helpful tips that will make things a bit easier for you:

  • Label EVERYTHING. Label all of your equipment as well as the ends of each cable. This makes things much easier should you ever need to change a cable or perform work on anything.
  • Multi-colored ethernet cables. Use different colors for each network (i.e. public, private, IP KVM, IPMI, etc.) Once again, this will make any work you need to perform much easier. You will be able to spend your time working, rather than finding what cable goes where.
  • We recommend using pre-built network cables. This saves time and expense. We suggest looking at the following suppliers:
  • Use crossover couplers instead of dedicated crossover cables. They're cheap, and, should you need to replace a cable, standard Cat5e/Cat6e cables are much easier to locate.
