System airflow is from the front to the rear of each enclosure:
• Airflow passes between drive carriers and through each enclosure.
• The combined power and cooling module exhausts air from the rear of each canister.
Ensure that your environment falls within the ranges that are listed in the following table.
Table 8. Temperature requirements
Environment
Operating
Non-operating
Transit
Note:
• – Max ambient temperature environment = 32C / 950 m
– Max altitude environment = 25C / 3,050 m
– Decrease the maximum air temperature by 1 degree C per 300 m above 950 m.
• The maximum ambient operating temperature when using an optical cable or discrete optical
transceiver is 32C, which includes all Ethernet (100 Gb) cables and InfiniBand (100 Gb EDR) that are
greater than or equal to 3 meter in length. The maximum ambient operating temperature when using
only copper cable is 35°C, which includes all Ethernet and InfiniBand cables less than 3 meter in length.
Dimensions and weight requirements for rack installation
Ensure that space is available in a standard 19" rack that is capable of supporting the enclosure. The rack
rail kit supports racks with threaded round and square rail mounting holes. The following table lists the
dimensions and weights of the enclosures:
