Installing an I/O module

You can install up to four I/O modules into the Flex System Carrier-Grade chassis. An Ethernet switch or a pass-thru module must be installed in I/O bay 1 and/or bay 2 whenever one or more compute nodes on-board Ethernet interface is active or there is an Ethernet I/O expansion card interfacing with I/O bay 1 and 2.

Before installing an I/O module, complete the following steps:
  1. Verify that the I/O module is compatible with the chassis. See Lenovo ServerProven compatibility.
  2. Read the installation instructions that come with the I/O module.

To install an I/O module, complete the following steps.

  1. Remove the I/O filler, if necessary. Open the release handles (rotate the top handle up and the bottom handle down).
  2. Slide the filler out of the bay.
  3. Open the release handles on the I/O module (rotate the top handle up and the bottom handle down).
  4. Align the I/O module with the bay on the chassis and slide the module into the module bay until it is seated.
  5. Close the release handles (rotate the top handle down and bottom handle up).

Warning: The intra-building port(s) (EN2092 I/O module Ethernet ports) of the equipment or subassembly are suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Attention: All CAT-5E cables used for the Flex System Carrier-Grade chassis must be shielded and grounded on both ends.
