Chapter 1: Setting Up The Me4 Series Expansion Enclosure - Dell EMC ME4 Series Getting Started Manual

Setting up the ME4 Series expansion
Consider the following best practices when setting up an ME4 Series expansion enclosure.
● Before connecting any cables between the storage system and the host server or expansion enclosure, physically label each
port and connector.
● Always follow proper power-up and power-down procedures when cycling power across the network. Verify that critical
network components are on separate power circuits.
WARNING: If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified
by the manufacturer.
NOTE: This product is intended for restricted access locations, such as a dedicated equipment room or equipment closet.
