In Rack Cooling? Check this out!

IMG_1315 Recently while touring one of the Data Centers we routinely maintain we ran across this really “cool” ( no pun intended ) device for in row cooling from APC.  It’s called the InRow RD.  And I have to tell you after being in the recent heat which the South Eastern United States experienced, these babies felt mighty good on a hot summers day to stand in front of! 

 

The devices are 42U high but are not as wide as a traditional 19” Data Rack, I believe they were 8” wide. 

 

Each system had six cooling fans which put out some serious cooling power.  

 

This particular unit was capable of pushing out 2290 CFM, which is a lot of cool air for a hot data center.

The InRow Direct Expansion product design closely couples the cooling with the IT heat load. This design prevents hot air recirculation, while improving cooling predictability and allowing for a pay as you grow environment. Available in self-contained, fluid cooled, and air-cooled configurations with or without humidity control, these products meet the diverse requirements for closets, server rooms, and data centers.

IT operators looking to improve efficiency or deploy higher density equipment will benefit from the modular design of the InRow Direct Expansion products.

The intelligent controls of the InRow Direct Expansion products actively adjust fan speed and refrigerant flow to match the IT heat load to maximize efficiency and address the dynamic demands of today's IT environments.

Unity Alias, can it be changed?

Cisco  Unity DC GC Tool Today I had an interesting and challenging ticket come my way.  The problem was the customer wanted to change their unity ( voice mail only ) accounts to conform to their corporate naming structure.  Funny enough, there is no “magic pill” to correcting this problem.  In fact, some firms would probably just say it cannot be done, or would tell the customer they would need to delete then recreate their VM boxes in Unity.  It absolutely can be done with a little attention to detail. 

The first step in the process is to configure the Active Directory information properly.  This includes changing the e-mail field which can be found on the General tab,  the User Logon Name which is under the Account tab, and the exchange alias ( which is the most important for the purposes of this blog entry ) and is located under the Exchange General tab.   

Once I had all the AD account information set up the way I wanted, I had to run a tool located in the Cisco Unity Tools depot, called DG/GC.  This tool allows you to sync the Unity accounts to the AD directory manually.  By default this sync occurs on a regular time interval ( in most cases it is run every 15 minutes ). 

DC GC can sync both the Domain Controller and the Global Catalog by pressing the “Force Reconnect” option.

AD Settings  

Either way, I found this process to be a little cumbersome because I had to manually touch 32 accounts, but in the long run, it would have saved me loads of time from deleting the VM box account and recreating it in AD, then re-importing it into Unity.  Best of all, the users are not aware this occurred at all, and they were able to save all their mailbox settings including greeting, pin, and voice mails. 

Food for thought, enjoy!

How to remove a Temp License???

One of the things that often comes up in the heat of the moment when installing a production UCCX server is the often sore subject of Licenses.  More times then not, the customer or the pre-sales folks forgot or miscalculated the number of agent licenses, or worse case scenario, you sold Standard licenses when you need to do a database dip and you need a Premium license.  Well how do you remove the temp license once you have ordered and registered the legit key?

CRS Script Editor Fundimentals - 4 Video Series

UCCX.Net,

I am please to announce the first of many video tutorials showing you how to use various technologies in and around the UCCX platform.  Eventually I hope to add videos in for creating basic, intermediate, and advanced scripts.  But for now we will take baby steps and start with the basics.  This is a four part video blog detailing out how to install, configure and setup, and navigate inside the CRS Script Editor which is the tool that is used to create Contact Center scripts.  Scripts are the “brains” of the call flow inside an IVR.

Video 1 – This video will show you the process to download and install the CRS Editor

Video 2 – This video walks you through the basic layout of the CRS Script Editor, logging in, etc.

Video 3 – Customizing the CRS Script Editor and creating a new script, editing variables, etc.

Video 4 – Wrapping it all up. 

 

As always, if you like the videos or want to leave me some feedback, feel free to email me directly. 

Enjoy,

Alex

Device Mobility

I am attaching a rather old ( but I think still relevant ) doc that covers the concepts of Device Mobility.  I am working with this in the CCIE Voice Lab now, one of the things I noticed was how well it plays with Local Route Lists.

PRI ISDN Plan and Type

Today I turned up a full PRI in Northern Virginia ( NoVA ). The carrier was Paetec. This was one of the first PRI's I have done in such a major metro area as DC/NoVA. Interestingly enough several things came out of this that might be worth mentioning.

The customers gateway was H.323 and they were running CUCM-BE 6. I configured the traditional Route Patterns, Route List, Route Group, and Gateway in CUCM-BE. The dial-peer's in the H.323 gateway proved to be quite problematic based on the carriers switch.

MPLS Bonded T1 Configuration

Hi Everyone,

I figured this little configuration snippet may help someone some day. I had to configure an MPLS circuit today for a customer who had a 2851 ISR router, with an MPLS circuit. The circuit featured 3 T1's that were to be bonded together for a 4.5 meg circuit.

For brevity sake I am only showing what is needed on the interfaces and for basic routing.
