Electrical Equipment Guidelines

The port adapter is designed to be removed and replaced while the system is operating without
presenting an electrical hazard or damage to the system.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent system failures. Each port adapter consists of
a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding,
connectors, and a handle are integral components of the carrier. Although the carrier helps protect the
boards, use an antistatic strap whenever handling the port adapter. Handle the carriers by the handle and
the carrier edges only; never touch the boards or connector pins.
OL-5418-07
– One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately
0.108-inch (2.743-mm) insulation, for a total wire diameter of approximately 0.27 inches
(6.858 mm). The wire length depends on your router location and site environment.
Two rack-mount brackets for mounting the chassis in the rack
One cable-management bracket
One AC power cable-retention clip (if you ordered a single AC power supply)
Four 12-24 x 0.5-in. screws to secure the rack-mount brackets to the chassis
Four 8-18 x .37-in. screws to secure the rack-mount brackets to a 19-inch rack
Four 8 x .375-in. screws to secure the rack-mount brackets to a 21–23-inch rack
One M4 x 20-mm screw to attach the cable-management bracket to the rack-mount bracket
Data service unit (DSU) to connect each serial port to an external network
T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link
Control (HDLC) synchronous serial data stream into a T1 data stream with the correct framing and
ones density to connect a serial port to a T1 network. (Some telephone systems require a minimum
number of 1 bits per time unit in a data stream, called ones density.) Several T1 CSU/DSU devices
are available as additional equipment, and most provide a V.35, EIA/TIA-449, or EIA-530 electrical
interface.
Ethernet transceiver
Token Ring multistation access unit (MSAU)
ESD-preventative wrist strap
Power cord
Appropriate cables to connect the router to the console and auxiliary ports
