Multi I/O cable NTRH0912
Used with 201i/202i servers, a multi I/O cable presents 2 network intefaces, and one RS-232 port, from an IPE slot 50-pin Amphenol (RJ-21). The standard cable is approximately 3 m (10 ft) long. If you need a longer length, use a RJ-45 female-to-female adapter to attach an additional CAT5 cable. A maximum length of 76 meters (250ft) is supported. Alternatively, you can use the pin diagram below to construct your own!

- Shield braid at amphenol connects to shields on COM1 & LANs
- COM1 is a shielded serial cable with male DB-9 end, its purpose is to connect to a modem for remote access.
- ELAN and CLAN are shielded ethernet cables with RJ-45 ends. Both have a ferrite bead on the RJ-45 end, and both go through a single ferrite bead at the amphenol end.
- If the modem port is not required: in lieu of an NTRH0912, simply cut the end off a network patch cable, and punch the Orange and Green pairs to RJ-21/BIX pairs 21 & 22 (ELAN), or 23 & 24 (CLAN).
- Shields and ferrite beads are your friends! They prevent RF interference both emanating from, and causing trouble to, your electronic devices. Shields also mitigate crashes due to electrostatic discharge.
