Single And Multiple Switch Arrangements - Nortel BayStack 5520-48T-PWR Install Manual

Before you begin this procedure, ensure that the equipment rack meets
these requirements:
•
A space equivalent to the rack height of the switch is provided for each
switch in an EIA or IEC standard 19-inch (48.2 centimeter) or TIA
23-inch (58.4 centimeter) equipment rack.
•
The rack is bolted to the floor and braced if necessary.
•
The rack is grounded to the same grounding electrode used by the
power service in the area. The ground path must be permanent and
must not exceed 1 ohm of resistance from the rack to the grounding
electrode.

"Stack arrangement" (page 31)
You can stack any of the 5000 Series switches. You can connect up to
eight 5500 Series devices in a stack to provide uninterrupted connectivity
for up to 384 ports. This stack is managed as a single unit.
You can connect up to 8 5600 Series devices in a stack to provide
uninterrupted connectivity for up to 384 ports. Bandwidth in a 5600 Series
stack is 144 Gbps.
You can connect a combination of 5500 and 5600 Series switches in a
stack of up to eight devices (this is called a hybrid stack). Bandwidth in
a hybrid stack is 80 Gbps.
Standalone arrangement
This module describes a standalone configuration.
Any one switch can operate in a standalone configuration. You can add
more switches as your traffic increases.
