CHAPTER 5: INSTALLING THE SWITCH
5.7 PORT CONNECTIVITY
Black Box recommends you distribute port groups across all four port pipes.
The EMS100G-32 switch has four port pipes, also known as packet processing pipelines. For the best buffer resource usage,
distribute the functional port groups, such as downlinks, uplinks, interchassis links, LAGs, and ECMP, across all four port pipes—0,
1, 2, and 3. If that is not possible, distribute the port groups across port pipes 0 and 2 or port pipes 1 and 3. For example, create a
two-port LAG using port 21 from port pipe 0 and port 5 from port pipe 2, as shown.
TABLE 5-2. PORT AND PIPE DISTRIBUTION

The connectivity between the front panel ports and the port pipes is shown.

5.8 POWERING UP THE SWITCH
Supply power to the switch after it is mounted in a rack or cabinet.
Black Box recommends reinspecting your switch before powering up. Verify the following:
The equipment is properly secured to the rack and properly grounded, recommended.
The equipment rack is properly mounted and grounded, recommended.
The ambient temperature around the unit, which may be higher than the room temperature, is within the limits specified for the
switch. For more information, see Chapter 1, Specifications.
There is sufficient airflow around the unit.
The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection devices.
All protective covers are in place.
NOTE: A US AC or DC power cable is included for powering up an AC or DC power supply. You must order all other power cables
separately.
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when
handling the switch and its components.
