PIMs and BRIMs

The suffix of the PIM’s product name, which follows the hyphen, specifies what media type and connector style the PIM provides. Typically any alphabetic characters indicate the media, while numerical characters indicate a special connector type for that media. The “F” in the example shown in Figure 4-2indicated that the PIM is for fiber optic media, while the “2” further indicates that the PIM provides Straight-Tip, or ST-type connectors.

EPIMs

EPIMs are Ethernet Port Interface Modules. An EPIM provides one shared or switched Ethernet connection to a single type of Ethernet media. EPIMs are typically used to make connections from workgroups to enterprise switches, data centers, or specialized equipment. The EPIMs that are available from Cabletron Systems and the types of cabling and connectors supported by each are listed below:

EPIM-A:	AUI (DB15 Female Connector)
EPIM-C:	Coaxial Cable (RG-58 Connector)
EPIM-F1:	Multimode Fiber Optics (SMA Connectors)
EPIM-F2:	Multimode Fiber Optics (ST Connectors)
EPIM-F3:	Single Mode Fiber Optics (ST Connectors)
EPIM-T:	Shielded or Unshielded Twisted Pair (RJ45 Connector)
EPIM-X:	AUI (DB15 Male Connector)

Fast Ethernet Interface Modules

Fast Ethernet Interface Modules are, in essence, EPIMs for the Fast Ethernet networking technology.

EPIM-100TX: Fast Ethernet UTP (RJ45 Connector)

EPIM-100FX: Fast Ethernet Multimode Fiber Optics (SC Connector)

EPIM-100F3: Fast Ethernet Single Mode Fiber Optics (SC Connector)

EPIM-100FMB: Fast Ethernet Multimode Fiber Optic Buffered Uplink (SC Connectors)

NOTE

Fast Ethernet Interface Modules will not operate in standard Ethernet devices. The reverse situation is also true.
