DANGER
The procedures in this manual are for qualified service personnel.
The following steps are required to ensure correct installation and operation.
1. Provide a space that is 8 rack units (8U) high, 61.19 cm (24.09 in.) deep, and 43.74 cm (17.22
in.) wide. One rack unit is equal to 4.45 cm (1.75 in.). If you are using the Air Intake Kit, you will
need a space that is 10U high to accommodate both the Intake Kit and the switch.
Plan to install the Brocade VDX 8770-4 with the port side facing the air-intake aisle. Airflow is
from the left side of the switch to the fan side. If you are using the Intake Air Duct rack kit for
mounting the Brocade VDX 8770-4, then the airflow is from the port side to the fan side.
Ensure that the rack is balanced and mechanically secured to provide stability in the event of
an earthquake and that the equipment does not exceed the rack’s weight limits.
NOTE
Doorways must be wider than 91 cm (36 in.) to accommodate the switch.
2. Ensure that dedicated electrical branch circuits with the following characteristics are available:
• Up to four dedicated fused 200–240 VAC, 50–60 Hz feeds or -48 VDC (one per power
supply)
• One cable for each power supply
CAUTION
Use a separate branch circuit for each AC power cord for redundancy in case one of the circuits
fails.
• Protected by a circuit breaker in accordance with local electrical codes
• Supply circuit, line fusing, and wire size adequate to the electrical rating on the switch
nameplate
