SCON-20L/22L Hardware Reference Manual
Power Cable Requirements
For units operating at 100-120V: The power cable required for domestic units is a UL
listed, CSA certified, 18/3 AWG, type SJT, cable (15-foot [4.57-meter] maximum). It is
terminated on one end by a 125V, 15A grounding type attachment plug. It is terminated
at the other end by a 125V, 15A parallel blade, grounding type attachment plug.
For units operating at 200-240V: The power cable required for domestic units is a UL
listed, CSA certified, 18/3 AWG, type SJT, cable (15-foot [4.57-meter] maximum). It is
terminated on one end by a 250V, 15A grounding type attachment plug. It is terminated
at the other end by a 250V, 15A tandem blade, grounding type attachment plug.
The power cable required for international units is an 18/3 AWG, type SJT, cable (15-
foot [4.57-meter] maximum). It is terminated on one end by a 250V, 15A grounding
type attachment plug body. It is terminated at the other end by a 250V, 15A grounding
type cord connector. The cord set is marked HAR to signify appropriate safety approvals.
The socket outlet must be nearby and easily accessible, per IEC 950 Sec. 1.7.2.
The installation site must provide a properly wired and grounded power outlet. Circuits
connected to air conditioners and devices that generate significant transient electrical
noise should be avoided.
Electrostatic discharge in the vicinity of the unit should be minimized by avoiding high
resistance floor material and carpeting that does not have antistatic properties, avoiding
the use of plastic seats and covers, and avoiding low humidity levels. The unit should be
located away from areas that generate electromagnetic interference (for example,
transformers, power distribution panels, and motors). The unit should not be installed
where the atmosphere contains corrosive elements that may damage the unit.
Cable runs should avoid areas that produce electromagnetic interference (for example,
near transformers, switching equipment, power distribution panels, and under carpets
where vacuum cleaning is done). Also, heavy equipment should not be moved or rolled
over the cable.
Connections
ESCON Channel Interface
An ESCON Controller (ESC), a PCI Feature Adaptor (PFA) board with a Luminex
ESCON board permanently connected/mounted in place, provides a single ESCON
Channel communications interface. The ESC provides a single channel attachment
interface for connecting the 20L/22L Console Concentrator to an ESCON director or to
a mainframe ESCON channel.
The fiber connection from the mainframe to the ESC shall be multimode 62.5/125 micron
cable for distances up to 3 kilometers with no directors, or 9 to 26 kilometers with 2
ESCON directors in series. Multimode 50/125 micron cable may also be used for
distances up to 2 kilometers with no directors, or 6 to 24 kilometers with 2 ESCON
directors in series.
