1754-HC1 IBM GCM16 Global Console Manager (1754-D1X)

The IBM 1754-HC1 is the machine type-model used to order the GCM16, the Global 2x2x16 Console Manager whose part number is 1754-D1X (feature 6694). It is a digital KVM-over-IP switch that also manages serial devices, so one appliance reaches servers, network switches, routers and power distribution units, including the server BIOS, over the existing IP network.

The GCM16 has 16 target ports and supports two local users and two remote users. Daisy-chaining extends it to 256 target systems, and a two-level tiered arrangement reaches 1024. Targets connect over CAT-5 cable with USB, PS/2, Virtual Media or Serial conversion options (43V6147, 39M2895, 39M2897, 46M5383, 46M5382).

Local video is VGA up to 1600x1200 or 1680x1050 widescreen, with two USB ports for keyboard and mouse and two more for a memory key or optical drive. Two gigabit Ethernet ports are redundant, and a serial port and a modem port are included for out-of-band access.

Access control covers a user database in the unit or a remote LDAP server, AES encryption, and Smart Card or Common Access Card support. IPv6 is supported, and the unit is managed through a web interface or Virtual Console Software.

It takes 100-240 V, 50/60 Hz input at 18 W, with redundant power supplies and two C13/C14 rack power cables. The carton also holds sidewall mounting hardware, a 1U filler panel, RJ45-DB9F and RJ45-DB9M adapters and 16 terminators for daisy-chaining.

IBM withdrew the GCM16 from marketing on October 8, 2025. The larger GCM32 is 1754-D2X (1754-HC2).
