Hot Swapping a Fan Unit on the
Netcrypt Bulk Encryptor
Netcrypt Bulk Encryptor
Overview
Introduction
The Netcrypt™ Bulk Encryptor is a powerful data encryption device that you can
use in your network to secure broadcast and on-demand applications in systems that
use MPEG transport over User Datagram Protocol (UDP), Internet Protocol (IP), and
Ethernet. A hot-swappable fan unit for the Netcrypt Bulk Encryptor provides a quick
and easy way to replace the fan. When you hot swap a fan, you do not need to
remove the bulk encryptor from the rack before replacing the fan. And, best of all,
the hot-swappable fan unit allows you to replace a failed fan without disrupting
service to your subscribers. This document provides instructions for replacing a fan
unit on the bulk encryptor by either hot swapping the fan unit, or by powering off,
disconnecting, and removing the bulk encryptor completely from the rack.

How to Identify the Fan that Failed
If a fan fails on the bulk encryptor, a front panel alarm light illuminates. You can
pull the bulk encryptor partially out of the rack to determine which fan you need to
replace. Any fan that is not spinning indicates a fan failure.

If you are using Cisco’s optional DBDS Alarm Management System to monitor
network elements, Netcrypt Bulk Encryptor alarms are monitored on the DNCS. If a
fan fails on the bulk encryptor the Alarm Management System issues a Fan Failure
alarm. The fans are numbered 1 to 5 from front to back on the Netcrypt Bulk
Encryptor. If fan 1 fails, the message “Fan 1 failure” appears. If fan 2 fails, the
message “Fan 2 failure” appears, and so forth.

When to Replace a Fan
Replace a failed fan as soon as you identify it has failed.
