Dew point within the range of 5.5º C to 15º C (41.9º F to 59.0º F)
Operating within the range supports the highest degree of equipment
reliability, even though the equipment data sheets may state wider ranges
of minimum and maximum temperature and humidy (for example, -40º C to
55º C and 5% to 95% RH). Continuous equipment operation at the minimum
and maximum limits is not recommended.
Keep panel sealed to avoid dust and/or animals and insects.
Inspect the installation site for moisture, loose wires or cables, and
excessive dust. Make sure that airflow is unobstructed around the switch
and into the air intake vents.
Check the device status reporting on syslog server. The log function is a file
that records information of a running operating system or software at a
device. Many applications use this for analysis purposes, as it keeps stored
running routines or physical connections information, such as active
Ethernet ports.
For computer usage, the log file format (known as syslog) is standardized
according to RFC 5424. This RFC does not specify the transport layer
protocol. UDP protocol usage for syslog applications is defined in RFC 5426,
and this document specifies that at least the 514 UDP port must be used for
syslog applications. Other ports, if applicable, should be configurable.
Reason Switches have the capability to send log messages to a dedicate log
server. The syslog level is divided in 4 categories: error (severity 3), warning
(severity 4), notice (severity 5) and informational (severity 6). When choosing
higher severity level, the equipment will send all messages from lower levels
plus the severity level selected. Thus, choosing informational severity level
allows the user to receive all log messages that the equipment can send.
Choosing error severity level the user will receive just error messages.
Further important information also can be monitored. The SNMP protocol
should be used.
The SNMP protocol was created in the mid 1990´s to increase the
management information allowed by network devices to send to
workstations. Creating a protocol to send standardized information over IP
network to a server has increase network maintenance and diagnostics
capability. There are dozens of RFC documents related to SNMP, such as the
RFC 1157 (A Simple Network Management Protocol). When using this
protocol, it is important to list relevant RFC document to the application.
Reason Switches have support to SNMPv1, SNMPv2c and SNMPv3 protocols.
All of the mentioned SNMP versions, besides the RFC 3584 standardized that
all versions can coexist in a given network. Thus, SNMPv1 networks can
include SNMPv3 or SNMPv2c protocols, but the capability of the SNMPv1
agents is not the same as the other version agents. When using different
