3.2.4 Connecting to a Power Source
This switch supports both AC and DC power supply modules.
3.2.4.1 Connecting to AC Power
To connect the 7210 SAS-M to a power source:
Step 1. Verify that the external AC power source has the following rating: 100-
240VAC, 50/60 Hz, 2A.
Step 2. Install the AC power module. Make sure the AC power module is powered
OFF before you plug the power cable in to the AC power source.
Step 3. Plug the power cable in to the AC power source.
Step 4. Power on the AC power module. Check the power module LEDs as the
7210 SAS-M is powered on to verify that the AC LED indicating external
power status is on, and that the +12V LED indicating internal power
conversion is on. If not, recheck the power supply and power cable
connections at the supply source and at the power module.
Step 5. If you have installed both primary and redundant power modules, verify that
the LEDs on both modules are lit as indicated in step 4.
Caution: The 7210 SAS-M 24F 2XFP ETR version must use the extended temperature
range power module.
Note: The switch is designed to accept up to two AC or two DC power modules. The switch
also accepts a single AC and single DC power module.
Note: In order to comply with the GR-1089 Lightning Criteria for Equipment Interfacing With
AC Power Ports, an external Surge Protective Device (Perma Power Model # PXD309) is
intended to be used at the AC input of the switch.
Note: A redundant AC power module may be hot swapped in. However, for safety
precautions the main power cord should be connected after the AC power module is
installed.
