Campus Network Engineering Meeting Notes - Power requirements going up for all TR's due to increased need for PoE
Full history of meeting notes on the agenda item "Power requirements going up for all TR's due to increased need for PoE".
- 15FEB21: We discussed how to get current power available. The new AP will be needing 60 to 90 watts. Neil let us know that our current power standard is two 20 amp circuits per closet. We discussed adding two 208 20 amp circuits to existing wiring closets. Most new electronic devices (switches, laptop, testing equipment...) that we use a power supply that is an auto-ranging and supports input voltages of 110/208. We discussed calculating power for each wiring closet versus having a standard implementation. We discussed if we still need 110 volt circuits. We discussed creating a list of closets with 3 or more switches. We discussed calculating PoE of all devices (AP's, phones, cameras...) currently connected to the edge switches. We believe we would do a one for one replacement of AP's of the new 60-90 watt AP once the current AP refresh project is completed. 3-5 year is expected before we would do the next AP refresh. We discussed including VOIP phones that are currently using power bricks. We discussed needing to see what we are currently storing in MRTG for power statistics. Chris Lund recommended using L21-20 for 3 phase 20 amps as is done in the datacenter since it gives 5700 watts and flexibility to get the outlets that are commonly needed. We discussed putting the power information in OpenDCIM/Netbox. We discussed coming up with a list of a few building to derive a process for determining power requirements. We discussed heat load increasing due to increasing power usage. Consensus seems to be to double the power and it will be close after the buildings have been converted to the current AP's. We discussed engaging the Electric Shop power engineer to help with this project. The buildings that have DC plants installed will help verify power used. Scott has a script that polls for power statistics. Mark Tinberg sent an email with the current power supplies being used by the switches. Dennis would like to have some information to look at in two weeks. Mark Karls is going to work on this with Scott. Keeping on agenda to discuss in two weeks.
- 01MAR21: Dennis did not get the information yet.
- 08MAR21: Dennis did not get the information he was looking for yet. Scott has a script that polls the switches for power information. Mark Karls showed us how to use Scott's script. Dennis needs more time to think about how we should proceed.
