Install the DLm in a properly equipped and well-ventilated computer
room.
DLm requires the environmental specifications outlined in
"Environmental data" on page
exceeds the specifications listed for both nonraised floor and raised
floor environments.
The Presite Survey, completed with the EMC Systems Engineer,
reports the Fibre connection (FICON) or Enterprise Systems
Connection (ESCON) cable lengths required for each host connection
to the DLm. From a physical planning perspective, review the routing
paths from the hosts to the DLm system. Resolve any physical access
issues prior to installation day.
Layout and space considerations are described in
options" on page
CAUTION
!
When moving the DLm bays down an incline, the rear of the bay
must go first and when moving up an incline, the rear of the bay
must go last.
Remote support is an important and integral part of the EMC
customer service and support strategy. Communication between the
EMC Customer Support Center and the DLm occurs either through
IP connections to the customer's local area network, or through the
external serial modem connected to the DLm, which requires
customers to provide one dedicated phone line for the modem.
