I like the integrated cable management.. because we all put cable
management with our switches, right? RIGHT? good!<br>

<p class="MsoNormal">Hi Guys,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We always mount our network switches in our racks
with the switches facing the rear, so that when you cable up servers,
you don’t have a mess of network cabling going from the front of the
rack to the back of the rack. This has worked well
for us for the last 10 years or so, but recently with providers like
NextDC doing cold isle containment, this means that switches are blowing
hot air into the cold aisle, and some people get unhappy with this.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We use Cisco 3750 switches which are 1RU, and they
blow hot air out the back of the switches, some models have side-to-back
airflow, but it still results in hot air being sent into the cold
aisle. I have always thought that this amount
of hot air was negligible, and wouldn’t even matter in the overall
scheme of things, as long as your servers were mounted around the right
way.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">How are other people handling this situation? I’m
not really keen on changing our rack standards and having to re-do the
entire cabling for racks across the 4 of our data centres that are using
cold isle containment!</p>
