5.2 Product
Description
An important feature of the LH8050A Hub is the use of individual Port
Modules (PMs) for flexible mixed-media connectivity to RJ-45 and fiber media.
Since the LH8050A’s have dual-speed capability per-port, the front port slots are
designed to support all standard Ethernet media types at 10 or 100Mps speed. Each
PM provides one port for connecting one Ethernet segment with its individual
connector type and media.
For a list and brief illustration of Port Module types, refer to Section 2.4
Each PM is individually described in the following sections.
