Overview Use this section if you have not ordered the DTC 16xx or the DTC 72MX with the RJ45 19” Distribution Panel as a factory-racked product (product numbers J2062AZ or J2070AZ). Chapter 1 of the HP DTC Cabling and Racking Guide includes information about HP computer racks and describes how to rack the DTC 72MX and the DTC 16xx family, which includes the DTC 16TN, DTC 16iX and DTC 16MX.

Page 9: Hp System Racks
HP System Racks The HP System Racks conform to the IEC and EIA standards for 19” (482.6 mm) racks. Any HP, or non-HP, equipment that conforms to these standards can be installed in one of these racks. The 1.1 meter and 1.6 meter system racks are measured in EIA (Electronic Industries Association) units.

Page 12: Guidelines For Racking Systems
Guidelines for Racking Systems The vertical mounting columns have a slot feature to help position and secure support rails. This makes installation of rails easier as they do not have to be held in position when they are bolted to a vertical column. It also ensures that rails can only be located in proper EIA unit increments.

Page 75: Making Your Own Cables
Making your own cables This chapter includes advice which you may ﬁnd useful when making your own cables to connect devices to ports on the Modem Distribution Panel, the Direct Distribution Panel, and the 24-port RJ45 Direct Distribution Panel. You will also ﬁnd some background information concerning the RS-232, RS-422, and RS-423 standards.
Page 76: Guidelines For Application
A note on standards Guidelines for application The RS-422 and RS-423 standards do not specify maximum distances or maximum data rates for connecting cables. These standards do, however, include “Guidelines for application” which give conservative values for maximum cable length and data rates based upon the following cable type: •...
Page 77 A note on standards RS-423 The RS-423 standard (also known as CCITT V.10) has a maximum data transmission rate of 100 kBaud at distances up to 250 feet/80 meters. It can be used at a maximum distance of 4000 feet/1200 meters at data rates less than or equal to 5 kBaud.
Page 78: Rs-422/Rs-423 Compatibility
A note on standards RS-422/RS-423 compatibility RS-422 and RS-423 are both compatible since they specify the same electrical characteristics for the receiver. However, when connecting devices with different baud rate and distance capabilities, the connection is limited to the baud rate and distance supported by the device with the slower/shorter distance speciﬁcation.
Page 79: Wiring
RS-422 and RS-423 are intended for long-distance connections in datacommunications applications. These long distances make the use of prefabricated cables difﬁcult and uneconomical. Consequently, there are presently no RS-422 or RS-423 datacommunication cables available from Hewlett-Packard. Instead, cables must be made using the advice provided in this document.
Page 80: Environmental Effects
A large ground potential difference may cause permanent damage to a system or to peripherals. Whilst Hewlett-Packard equipment is protected against this kind of damage, no such protection can be one hundred percent effective.
Page 81: Dtc And Standard Cables
DTC and standard cables DTC and standard cables The DTC 72MX and DTC 16xx family provide RS-232-D or RS-423 ports with RJ45, DB25 or Telco 50-pin connectors. The DTC units support the distances provided by the RS-232/RS-423 standards, given in the table below. Additionally, HP has tested, in favourable environmental conditions, the distances given in the ﬁnal column of the table below.

Page 90: Cabling Tips
Cabling Tips Cabling Tips You may ﬁnd the advice in this section useful when making your own cables, planning a cabling scheme and making cable connections. Twisted pair cables When connecting twisted pair cables to cross-connect blocks, keep each pair twisted all the way up to the connecting pins of the cross-connect block.
Page 91: Adapting To Cabling Systems
Adapting to Cabling Systems This chapter provides information for using a HP DTC unit with the following cabling systems: • ATT356A • 10BaseT • ATT258A A DTC unit can be linked to devices, such as terminals or printers, using any of the cabling systems listed above.

Page 93: Adapting To Att356A Cabling System
Adapting to ATT356A cabling system Adapting to ATT356A cabling system ATT356A is a cabling system using 6 wires per port and provides 8 ports per 25 pair cables (or 50-pin telco-like connectors). The DTC is directly compatible with the ATT356A cabling system, providing 8 direct connect RS-232 or RS-423 ports on a 50-pin connector.

Adapting to a 10BaseT cabling system Adapting to a 10BaseT cabling system The 10BaseT cabling system uses 4 wires per port and provides 12 ports on a 25 pair cable (or on a 50-pin telco-like connector). The DTC provides 8 direct connect RS-232 or RS-423 ports on a 50-pin connector. The following table provides a cabling conversion using cross-connect blocks (punch down blocks) from ATT356A to 10BaseT.
