The following port numbering guidelines apply to all I/O modules except the network daughter card:
● The physical interface name format for the remaining I/O module slots is ethXy, where X is the slot number and y is an
alphanumeric character. For example, eth0a.
● For most horizontal I/O module NIC interfaces, the port numbering goes from left to right, with ethXa on the left.
○ Slots 7 and 8 are reversed, with ethXa on the right.
Slot assignments
The following table lists the slot assignments for the supported I/O modules.

Steps
1. For 10 GBASE-T connections, use one of the following:
● Unshielded Cat 6 cables with RJ-45 connectors that do not exceed 55m
● Cat 6A cables with RJ-45 connectors that do not exceed 100m
2. For 10 GbE-SFP+ optical connections, refer to the list of qualified adapters and use an OM1 160 MHz (2 to 26m), OM1 200
MHz (2 to 33m), OM2 400 MHz, (2 to 66m), OM2 500 MHz (2 to 82m), OM3 1500 MHz (2 to 300m), or OM 4 3500 MHz
(2 to 400m) SFP+ optical cable.
3. For FC connections, use a qualified OM1, OM2, or OM3 Fibre Channel optical cable:

Connecting disk shelf power cables
Prerequisites
Each disk shelf has two power supplies. Connect each power supply to redundant AC power sources, so the loss of one power
supply or one power source does not cause the shelf to power off.
About this task
ES40 shelves have one power cord per power supply for a total of two power cords.
