LRS-24Installation and Operation Manual Chapter 1 Introduction

Power Supplies

LRS-24 operates with single or dual, AC or DC power supplies. Each power supply supports a full LRS-24 hub, including modem cards. Redundant power supply can be replaced during operation, without affecting system performance (hot-swapping).

Cards in the LRS-24 chassis are capable of providing remote power feeding for repeaters and remote standalone modems. To provide remote power feeding order a separate standalone power supply, LRS-PS-FEED.

Versions

Two different physical versions of the LRS-24 hub are available:

•ANSI − card insertion, LEDs and switches are at the front, but cable connections are at the rear of the hub. This compact, 4U high unit complies with the American ANSI standard. Cards can be hot-swapped without removing cables.

•ETSI − card insertion, LEDs, switches and cable connections are at the front. This version is 30 cm high (almost 6U), and complies with European ETSI standard. Cards can be hot-swapped without removing cables.
