Error Codes and Definitions
Incrementing Counter Errors
Table 5-1. Incrementing Counter Errors
Counter
Alignment Errors
Definition
Alignment errors are a count of the number of frames received that do not end with an even number of octets and have a bad CRC FCS error count is the number of frames that were transmitted or received with a bad checksum (CRC value) in the Ethernet frame. These frames are dropped and not propagated onto other ports. This is an indication that the internal transmit buffer is full.
Cause of Incrementing Counters
Result of collisions at half-duplex, duplex mismatch, bad hardware (NIC, cable, or port) or a connected device generating frames that do not end with on an octet and have a bad FCS Result of collisions at half-duplex, duplex mismatch, bad hardware (NIC, cable, or port) or a connected device generating frames with bad FCS Indication of excessive input rates of traffic. This is also an indication of transmit buffer being full. The counter should only increment in situations in which the switch is unable to forward out the port at a desired rate. Situations such as excessive collisions and 10MB ports cause the transmit buffer to become full. Indication of excessive output rates of traffic. This is also an indication of the receive buffer being full. This counter should be zero unless there is excessive traffic through the switch. Indication of a bad frame generated by the connected device. Indication of a half-duplex configuration (normal for half duplex) Indication of a half-duplex configuration (normal for half duplex) Indication of faulty hardware (NIC, cable or switch port) or a duplex mismatch

This is an indication that the receive buffer is full
UnderSize Single Collisions Multiple Collisions Late Collisions
These are frames that are smaller than 64 bytes (including FCS) and have a good FCS value Number of times the transmitting port had one collision before successfully transmitting the frame to the media Number of times the transmitting port had more than one collision before successfully transmitting the frame to the media Two devices transmit at the same time and neither side of the connection detects a collision. The time to propagate the signal from one end of the network to another is longer than the time to put the entire packet on the network. The two devices that cause the late collision never see that the other is sending until after it puts the entire packet on the network. Late collisions are detected by the transmitter after the first time slot of the 64 byte transmit time occurs. They are only detected during transmissions of packets longer than 64 bytes. Its detection is exactly the same as it is for a normal collision; it just happens later than it does for a normal collision. Number of frames dropped after 16 attempts to send the packet resulted in 16 collisions Occurs every time an Ethernet controller wants to send data and the counter is incriminated when there is an error in the process. Frames smaller than 64 bytes with a bad FCS value Frames that are greater than 1518 bytes and have a bad FCS value
Excessive Collisions Carrier Sense Runts Giants
Indication of over utilization of the switch port at half-duplex or duplex mismatch Indication of faulty hardware (NIC, cable or switch port) Indication of the result of collisions, possible duplex mismatch Indication of faulty hardware

6 Testing Product Assurance
Testing Product Assurance
Before using the Information Center system clinically with patients, proper performance of the system should be verified. This section includes a series of Product Assurance Tests that should be performed after system installation and any system repair or upgrade to verify system functionality. Notes These validation tests do not check all system specifications but are intended to verify performance of the primary features of Information Center functionality. However, successful completion of the performance tests should yield a fully functioning system. When performing product assurance tests, Information Centers must be connected to the SDN or Clinical Network.
Visual Tests
Prior to using the Philips system with patients, all system components, cables, and connectors should be thoroughly visually inspected. Step 1. Check all components of the Information Center system for signs of mechanical damage. If damage to a component is found, assess the damage to determine if repair or replacement is required. Repair or replace the component as required before continuing the Product Assurance Tests. Cables Step 2. Check all cables of the Information Center system for signs of abrasion, wear, or other damage. If any cable shows evidence of damage, repair or replace the cable prior to using the Information Center system for patient monitoring.
System Components
Connectors
Step 3. Check all cable connectors for signs of mechanical damage and each cable connection for connection integrity. If any cable connector shows signs of damage, replace the cable prior to using the Information Center system for patient monitoring. Step 4. Check that all cable connectors are securely fastened to the rear of each device.
