Overview Overview The Departmental Switch Models DS-16B2 and DS-32B2 are fibre channel gigabit switches that support link speeds up to 2 Gb/s. Each port can automatically negotiate to the highest common speed of all devices connected to the port. The ports are compatible with small form factor pluggable media (SFPs), are universal, self configuring, and are capable of individually becoming a fabric-enabled port (F_Port), fabric loop enabled port (FL_Port), or an expansion port (E_Port).

Device Placement Requirements Device Placement Requirements There are no restrictions on the location of the DS-xxB2 switch in the rack/cabinet. Switches are typically located at the top of the rack/cabinet. Power distribution must support the number of outlets required for the switch and the switch power rating listed in Table 2 on page 3.

Installing the DS-xxB2 Rails Assembling the Rails To assemble the rails: 1. Place the front rail down on a table. 2. Insert the slots of the rear adjustable rail onto the threaded posts on the front rail. Be sure that the lip on the top of the rear adjustable rail slides over the top of the slot on the front rail, thereby capturing the ac power cord. 3. Secure the adjustable rail to the front rail with two #10 flat washers and M5 keps nuts. Leave the keps nuts finger tight (see Figure 11).
