Chapter 7 Preliminary Steps Before Installing
Note An inventory of the installed cards is taped to the BPX switch. The inventory states each
card's serial number, revision number, and slot number (serial and revision numbers are
also found on the component side of each card).

Safety Requirements

This section details safety information for system planners, installers, and maintenance personnel.
The mechanical design of the BPX switch prevents any access to exposed voltages without the use of
tools. When installed properly, all front and rear cards are mechanically held captive.
Warning For protection against shock hazard, verify that all power cords or cables are
disconnected before servicing the unit (there may be more than one power cable). The
highest voltage that may be present in the node when powered up is 264 VAC (AC
systems) or 56 VDC (DC systems).

CEPT Requirements

All apparatus (such as, 48 VDC power supplies) connected to the BPX switch must comply with
BS6301 or EN60950.

EMI Requirements

Compliance with emission regulations depends upon adherence to the installation steps in this manual,
including installation of faceplates for all slots and the use of shielded cables between systems.

Laser Safety Guidelines

The optical ports contain an information label as shown in Figure 7-1.
