6 Acuity Welch Allyn Network installation
Signal strength First wireless signal: RSSI Value
-65dBm for (802.11a APs set to 25mW). Second wireless signal:
RSSI Value
-70dBm for (802.11a APs set to 25mW).
Wireless Dropped packets and loss of connectivity due to
poor wireless coverage.
SNMP read-only access Welch Allyn servers (Acuity systems) shall
have SNMP read-only access to Aruba controllers to log performance
data and generate alerts. Wired, wireless Limited ability to proactively respond to system
issues. Debugging by Welch Allyn Remote
Technical may not be possible. Extended
troubleshooting times.
Spanning Tree Protocol (STP) STP should be turned off for the
Welch Allyn specific VLAN/SSID. Use resilient links (spanning port
fast) for all wired interfaces connected to continuous monitors,
wireless controllers, or Welch Allyn Servers. Wired, wireless Dropped connections.
Mismatched connections Connections between gigabit and
FastEthernet interfaces should be avoided. If these interfaces are
configured, use them for light traffic only, and do not rely on auto-
negotiation. Ensure that you configure speed and duplex settings to
100Mbps and Full Duplex. Wired Unreliable network connection, severely affected
appliances connected through the interface.
Connection speed All Acuity systems must be connected to the
network using the same Ethernet speed. Wired Dropped packets, data loss.
UDP broadcast forwarding Allow UDP broadcasts on ports 7711-
7720 from Welch Allyn VLAN to the Acuity Central station. Wired Connections cannot be established.
Wired connection Interconnects between all switches and all Aruba
WLAN controllers with gigabit Ethernet. Wired With only 100Mbs connections dropped packets
and data loss can occur.
1. The 7% bandwidth allocation will support up to 20 connected Welch Allyn patient monitors per AP. If no Welch Allyn patient monitors are associated with the
AP the bandwidth is free to be used by other devices.
