2.4.2.1RM-CPU

Each RM-CPU contains one K6-2 [300 MHz] processor and two main memory slots. Each memory slot accepts a 64 MB memory module (MS64) and a 128 MB memory module (MS128), thus being able to configure up to 256 MB of memory. In addition, each RM-CPU of GR2000-4S, GR2000-6H, GR2000-10H, and GR2000-20H includes one RS-232C AUX port.

2.4.2.2RM-IO

Each RM-IO has one RS232 console port, two memory card (MC) slots, one 10BASE-T port, and a packet-forwarding ASIC.

2.4.2.3RMB-CPU

Each RMB-CPU has a common Pentium III (850 MHz) and four main storage (MS) slots. Since the main storage of 256 bytes (MS256) can be mounted, a memory of 1G bytes as maximum can be mounted.

Being different from RM-IO, BCU-S850S, BCU-H850H, BCU-M850H, and BCU-L850H have the RS-232C AUX board in RMB-IO.

2.4.2.4RMB-IO

RMB-IO has two RS232C console boards, two memory card (MC) mechanism slots, one board of 10BASE-T/100BASE-TX, and a packet forwarding engine (Packet Forwarding ASIC).

Duplication of BCU is possible only in GR2000-6H, GR2000-10H and GR2000-20H by mounting two sets of BCU.
