Replacing an I/O module

Use these instructions to install an I/O module in the Flex System Carrier-Grade chassis. You can install an I/O module while the Flex System Carrier-Grade chassis is powered on. For redundancy support, you must install I/O modules of the same type in I/O module bays 1 and 2, and I/O modules of the same type in bays 3 and 4 of the chassis.

Before you install an I/O module, complete the following steps:
  1. Read the installation instructions that were provided for the I/O module. I/O module documentation is available from the Flex System network devices information page.
  2. Verify that the I/O module is compatible with the chassis. See Lenovo ServerProven compatibility.

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).
After you install the I/O module, connect all cables to the module.

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.
