Existing Switch Specifications
Meru Networks 11n AP300 series APs can operate at maximum 300Mbps dual stream 11N
data rates on both Wi-Fi band radios 802. 11bgn and 802. 11an concurrently while using the
most prevalent PoE switch port type, a single standard 802.3af or 802.3at port; however there
are a few configuration considerations with regards to MIMO that need to be taken into
account, please review chart below. Knowing the PoE capabilities up front can help ensure
optimal configuration from the start.
The recommendations for radio MIMO settings for power options are provided below.
802.af PoE Usage
When using System Director 3.6/4.0 and 802.3afPoE, Meru supports radios set to any MIMO
settings except 3x3 on dual radios. This is because two radios set to 3x3 MIMO using an
802.3af switch may not have enough power if the cable is too long. Shorter cables frequently
work, however. Meru supports:
•
Single 3x3 radio
•
Dual 2x2 radios
•
Dual radio with one set to 2x2 and the other one set to 3x3
When using System Director 4.0 and 802.3af, the AP300 MIMO configuration is limited to the
following:
•
3x3 for the 5 GHz radio
•
2x2 for the 2.4 GHz radio
802.3at PoE Usage
When using System Director 3.6/4.0 and 802.3at, the following radio combinations are
recommended:
•
Single 3x3 radio
•
Dual 2x2 radios
•
Dual radio with one set to 2x2 and the other one set to 3x3
•
Dual 3x3 radios are recommended with a limitation.
Use 802.3at power for two 3x3 MIMO radios when the switch has a high enough power
output to support all devices on the PoE.
Site Data Collection Form
The Meru Networks Professional Services team has created a Site Data Collection form to
assist with gathering the system requirements. This form will help ensure that important
questions are asked and answered at the start of the project. For a copy of Site Data
Collection form please contact Meru Professional Service.
