Figure 49: DC Power Socket on the Summit X450a-24tDC Switch
NOTE
Figure 49 shows the rear panel of the Summit X450a-24tDC switch. The rear panel of the Summit X450a-24xDC
and Summit X450a-48tDC switches may vary slightly; however, the DC power socket is of the same type and the
connection process is the same for all DC-powered switches.
2 Tighten the retainer nut on the connector until it is finger-tight.
3 Energize the DC circuit.
Removing a Summit X450a-48tDC Switch from a Rack
WARNING!
Be sure to disconnect all power cables before you disconnect the chassis ground wire.
CAUTION
Be sure that proper ESD controls are in use before switch maintenance is performed. This includes but is not
limited to wrist straps that are grounded to the switch chassis and earth grounds.
To remove a DC-powered Summit switch from an equipment rack:
1 De-energize the DC circuit for all power connections.
2 Loosen the retainer nut and unplug the DC power connector from the DC power supply socket on
the rear of the switch.
3 Disconnect the Summit switch from the redundant power supply (if applicable).
4 On a Summit X450a-48tDC switch, loosen and remove the grounding screw from the back of the
switch enclosure. Move the ground wire out of the way.
5 Loosen and remove the four rack system mount screws holding the switch in place against the
system rack.
6 Carefully remove the switch from the rack and place it on a secure, flat surface.
