Rack Mounting
If rack-mounted units are installed in a closed or multi-rack assembly,
they may require further evaluation by certification agencies. The
following items must be considered:
1. The ambient temperature within the rack may be greater than
room ambient temperature. Installation should be such that the
amount of air flow required for safe operation is not compromised.
The maximum temperature for equipment in this environment is
40
°
C. Consideration should be given to the maximum rated
ambient temperature.
2. Installation should be such that a hazardous stability condition is
not inadvertently created due to uneven loading.
Network Connections
Connecting an Ethernet Device to a 10Base-T or 100Base-TX Port
The 10/100Base-TX ports on the AT-8116 are designed to be connected
directly to a workstation, using a standard straight-through patch
cable. In order to cascade switches or connect a hub to the switch, a
crossover cable must be used. The RJ45 ports are defined as MDI-X
ports.
The cable connections to the 10/100 ports should be UTP Category 5,
and cable length is limited to 100 meters on each port. Figure 3 and
Figure 4 shows the pin assignments for the RJ45 connector.
Note
Cables must comply with the ANSI/TIA/EIA specification,
commonly referred to as T568A or T568B.
