The Magnum 4K8R is like the 4K8F except that the front panel has the
LEDs, and all the connecting ports and power feeds are in the back. This is convenient
for rack-mounting where cabling is accessed from the rear of the rack while the operating
status LEDs are monitored from the front. Typically such arrangements are found in
Telco rack installations.
