CRBRIM-W/T
CHAPTER 3: Preparing for Installation
3.6.2 Serial Connections
Two serial interface ports are located on the faceplate of the BRIM to the left of
the console connector. The ports are labeled S0 and S1. The serial ports are 60-pin,
D-type subconnectors. All serial interfaces except the EIA-530 can be configured
as DCE, using a DCE cable. All DTE serial ports require that external clocking be
provided by a CSU/DSU or modem.
You must use a special serial cable to connect the router to a modem or CSU/DSU.
This cable is available from Cabletron and is usually ordered with the system. The
cable uses a DB-60 connector on the chassis end. See Appendix A, for cable
specifications. For ordering information, contact Cabletron Systems Technical
Support.

Inspecting the System
Do not unpack the CRBRIM-W/T until you are prepared to install it. If the final
installation site will not be ready for some time, keep the module in its shipping
container to prevent accidental damage. The CRBRIM-W/T package includes the
following:
•
CRBRIM-W/T module
•
Console cable (RJ45) with RJ45-to-DB-25 adapter
•
Token Ring cable (CRBRIM-W/T to RJ45)
•
Hardware User’s Guide
•
ESD Wrist Strap
Inspect all items for shipping damage. If anything appears damaged, or if you
encounter problems when installing or configuring your system, contact Cabletron
Systems Technical Support.
Due to the small size of the pins on the DB-60 serial connector,
attempting to manufacture your own serial cables is not
recommended.
