1754-A1X IBM LCM8 Local 1×8 Console Manager

The IBM 1754-A1X is the Local 1x8 Console Manager, the LCM8, an analog keyboard-video-mouse switch with eight analog rack interface ports and one local user. Its feature-code machine type-model is 1754-HC3 (feature 0725).

Each target server connects over standard CAT-5 cable through a conversion option at the server end: the USB option 43V6147 or four-pack 39M2895, the PS/2 option 39M2897, or the Virtual Media option 46M5383. The serial conversion option 46M5382 is not supported on this unit. Up to 128 servers can be reached by daisy-chaining or by tiering switches.

The local user plugs in a VGA display and USB keyboard and mouse, with extra USB ports for a memory key, optical drive or CAC reader. Video goes up to 1600x1200 (4:3) or 1680x1050 (widescreen). Two-factor authentication with a CCID-compliant smart card reader is supported, and IPv6, password protection, a serial port and a 10/100 Ethernet port are built in.

Remote access is an option: the 1754 LCM Digital Activation Key, part number 81Y2393, is a USB key that turns the unit into a digital switch with one remote user. Firmware updates for the switch go through Ethernet or the serial port.

The unit draws 8.5 W typically and 15 W at most from 100-240 V, 50/60 Hz input. The carton holds the eight-port switch, sidewall mounting hardware, a 1U filler panel, a 1.5 m C13/C14 rack power cable, an RJ45-DB9F adapter for the Setup port, an RJ45-DB9M adapter for the Modem port and eight terminators for daisy-chaining.

Its larger sibling, the LCM16 (1754-A2X), has 16 ports and two local users; the LCM16 was withdrawn from marketing on October 8, 2025.
