There is no upgrade from a Model 3012 to a Model 3024 since it would not
provide an economical method of adding ports. Note that the high degree of stacking of
Magnum 3000s - up to 20 units! - provides essentially unlimited expansion of the number
of users by adding more units to the stack.
2.5 Rear Bonus Slot, Port Modules (PMs)
The Magnum 3012s and 3024s are each equipped with a bonus slot on the rear
of the unit. This slot may be optionally configured at the time of order with any one of
six Repeater Port Modules (RPMs) or four Bridge Port Modules (BPMs) to implement an
extra port. The optional bonus port may be used for any purpose, such as an Ethernet
coax backbone connection, or as a micro-bridge segment isolation unit. The RPMs
support any of six different media types: BNC (ThinNet), AUI (ThickNet), DTE (male
AUI), ST & SC (multi-mode Fiber), SMF (single-mode Fiber), and RJ-45 (UTP and
STP). The BPMs support any of four media types: BNC, AUI, ST, and RJ-45 (UTP and
STP). Normally, a maximum of one BPM should be used in a stack.
Each PM is equipped with its own media connector type. (For additional
information and specifications of individual PMs, see Section 4 of this manual.) The
assortment of standard network connector types for each RPM is shown in Figure 2.5a.
