Your Success Story


It has been a pleasure working with you and your company.  I really appreciate the extra effort that you and Jack have put forward on our behalf to supply us with the materials that we needed.  I will definitely be touching base with you again in the future as we are planning on acquiring several more of these items to facilitate the upgrade of our existing locations as well and our new store openings.

Thank you again for all of your time and effort.

Information Support Concepts (ISC) announces the launch of new, more capable Uninterruptible Power Supplies (UPSs).  There are four new series of UPSs available.  Each one is more capable than the series it replaced, with higher power factors and new options.  All series are RoHS compliant, and use the same management software.  This provides great commonality should clients need different series UPSs for different applications.  Larger capacity units (EnterprisePlus and Endeavor) have load shedding functions to ensure the most critical components continuously receive power.
  • The EN series standby UPS is for small office or home office applications.  Identical form factors for 600VA/300W and 400VA/200w versions provide better functionality.
  • The ETR series is a small form factor tower unit for small applications with servers and related equipment.  Perfect for an individual work station.
  • The EnterprisePlus series has power factors of 80% and above, an EPO feature, and can accept an optional SNMP card with or without an environmental sensor probe.
  • The Endeavor series provides the latest technology, high power factor, an EPO feature, and can accept an optional SNMP card with or without an environmental sensor probe.
  • Environmental Sensors controlled through SNMP cards are now viable options for the existing CPE and Enterprise series as well.

With the new series available, and the new features that can be added as options to the existing series, the UPS line from ISC can provide outstanding service for the most demanding applications.

Killing Power When Needed
Advice For Shutting Off Power In Emergencies

Usually when discussing power  for a data center environment, the discussion revolves around UPSs (uninterruptible power supplies) and backup generators. Uptime and availability are the primary duties of the data center, so having redundant power and plans for how to survive temporary or short-term power outages is a key component of managing a data center.

There are times, though, when not having power is a good thing. If equipment is on fire or if an employee has come in contact with open power and is being electrocuted, you not only want to have no power, but you want no power immediately. In the event that a sprinkler system is triggered or there is a flood of some sort, you need to be able to shut down power quickly to minimize the damage done to the equipment by the water.

NEC Mandate

While just about any data center manager would agree that the safety of her employees comes before availability and uptime, it is also mandated by NEC (National Electrical Code) Section 645-10. The code states that power to HVAC and computer equipment must be terminated by switches at the exit doors of the data center to facilitate an immediate shutdown in the event of an emergency.

The EPO (emergency power off) circuit should be triggered by a highly visible, easily accessible, illuminated switch. Basically, personnel need to be able to locate the EPO switch quickly, even in a blackout or under catastrophic conditions.

The converse is also true, though. You do not want the EPO circuit to be tripped unless there is a compelling and immediate need to kill power. To prevent an accidental shutdown, the EPO switch should also be guarded or protected in some way. Typically, the EPO switch is a large, red button shielded behind a plastic case of some sort.

Local Or Global

Depending on the configuration and needs of your data center, you may have more than one EPO circuit. You can segregate equipment into different functional groups, such as critical and noncritical, or by group or department, or just based on physical location within the data center. You can then have local EPO circuits that will kill power for just that subset of equipment rather than the entire data center all at once.

Even if you opt to deploy localized EPO circuits, you still need a global or master EPO circuit that will kill power to the entire data center. The local EPO switches can be located throughout the data center in proximity to the equipment they control, while the master EPO circuit should be the large red button in the plastic case at the entrance to the data center.

To Trip Or Not To Trip

Once the EPO is implemented, you have to focus on defining how or when it is acceptable to trip it. A clearly defined policy and proper training will help personnel make the right decision quickly in an emergency.

You don’t want lives to be endangered by employees who do not understand the process for killing power or who second-guess the conditions under which power should be shut off. By the same token, you don’t want “trigger-happy" personnel shutting off power when it is not truly warranted.

Make sure that personnel who work in the data center are properly trained to function safely and that they understand the procedures to execute in the event of an emergency. The uptime of the employees is more important than the uptime of the data center.

The winner was Richard Wilkins.  Congratulations!


A Kevinism is a funny or intriguing statement or idea from our Vice President of Sales, Kevin Hunt.  Kevin is a big fan of Sandra Bullock, Pizza Inn black olive pizza, and Dr. Pepper (not necessarily in that order).  He is not a big fan of Chinese food, seafood, or other types of "dead" stuff.

This month we have a couple of new things.  One is Kevin going off on a tangent, while the other is a new product.

1.  Recently the area around the Ranger Ballpark in Arlington (recently renamed after temporarily being called Ameriquest Field in Arlington) has been getting some street renovations.  Streets have been blocked off for construction, parking lots have moved, and our routes to various restaurants in Arlington have had to be adjusted to accommodate the activity.  One day we happened to go by a parking lot with a sign that said "general parking."  Kevin immediately commented that he did not think there were that many Generals that wanted to attend Ranger games, and he wondered where all the other types of people (civilians and non-flag ranks) would be allowed to park.

2.  Kevin's newest product is the Soygarette.  We have a few people in the office who smoke cigarettes, and in most cases they are trying to quit.  However, one person has no intention of quitting, so Kevin suggested that something made from soy instead of tobacco might be much healthier if they did not want to stop smoking cigarettes.  He coined the term Soygarette as the product that would do this.

More Rackmount Ranger Jokes


     Since introducing the live version of the Rackmount Ranger in March (see March newsletter), we have been brainstorming on how to take advantage of our new "superhero."  We have planned some video shoots, and there may be some personal appearances upcoming.  In addition, the Rackmount Ranger recently got a check for $409.50 from a large and highly regarded private university in California.  It should have been made out to Information Support Concepts, but it is always good to be recognized!  Any publicity is good publicity.

We have also been playing around with what I call "Rackmount Ranger Jokes."  These jokes are simple, and very similar to the "Elephant jokes" that were popular in the sixties.  A typical elephant joke went like this:

     Why did the elephant paint his toenails red?  So he could hide in Cherry trees.

     Rackmount Ranger jokes are a similar question and answer format, but revolve around the Rackmount Ranger's personal preferences.  In addition, there is a theme to these preferences.  Here are some contributions from newsletter readers.

     What is the Rackmount Ranger's favorite food?  Red Snapper

     What is the Rackmount Ranger's favorite vacation spot?  Red Mountain Resort in Rossland, BC

     What is the Rackmount Ranger's favorite location mentioned in the Bible?  The Red Sea

     What is the Rackmount Ranger's favorite planet?  Mars (the red planet).  See this month's trivia question.

     What is the Rackmount Ranger's favorite school district?  Mars Area School District, Mars PA (see immediately preceding line)

     What is the Rackmount Ranger's favorite charity organization?  The American Red Cross

     What is the Rackmount Ranger's favorite restaurant?  Red Lobster

     What is the Rackmount Ranger's favorite hotel?  The Red Roof Inn

     What is the Rackmount Ranger's favorite Linux distribution?  Red Hat

     What is the Rackmount Ranger's favorite professional hockey team?  Detroit Red Wings

     What is the Rackmount Ranger's favorite children's book?  Clifford, the big red dog

     What is the Rackmount Ranger's favorite childhood game?  Red Rover

     What is the Rackmount Ranger's favorite pirate legend?  Red Beard (note that Captain Jack Sparrow is a close second).

     What is the Rackmount Ranger's favorite cowboy/western movie?  Barbarossa (Spanish for red beard)

     We hope you have enjoyed the list so far.  You have probably already thought of one or two that could be added to the list.  I am happy to review them and possibly include them in a future newsletter.  If you will send them to me, and we publish them, you will get a suitable prize.  I am thinking a virtually indestructible keyboard or virtually indestructible mouse (optical, USB) might be nice prizes to award.  I look forward to getting your submissions.

    As always, thanks for reading, and I hope you enjoyed the newsletter this month.
